			== History ==
	'''Gracenote''' is a commercial enterprise which maintains and licenses a database containing information about the contents of audio CDs. The database is accessible online over the Internet. Computer software applications such as ] that are capable of playing CDs use Gracenote's ] or similar commercial services such as ]'s ] and ], or open-source projects such as ] and ]. These programs generally offer the option of contributing track listings, and most of the track listings in the Gracenote database are voluntary contributions by individual users of CD-player software.
			Gracenote began in 1993 as an open-source project involving a CD player program named xmcd and an associated database named ]. xmcd and CDDB were created by Ti Kan and Steve Scherf. Because CDs do not contain any digitally-encoded information about their contents, Kan and Scherf devised a technology that identifies and looks up CDs based on TOC information stored at the beginning of each disc. A TOC, or Table of Contents, is a list of offsets corresponding to the start of each track on a CD. Its original database was created from and continues to receive voluntary contributions from users. This led to a ] when Gracenote became commercialized.

			On April 22, 2008, ] announced that it would acquire Gracenote for $260 million.<ref> {{webarchive \|url=https://web.archive.org/web/20100604174219/http://www.gracenote.com/company_info/press/042208/ \|date=June 4, 2010 }}</ref> The acquisition was completed on June 2, 2008.<ref> {{webarchive \|url=https://web.archive.org/web/20100516050155/http://www.gracenote.com/company_info/press/060208/ \|date=May 16, 2010 }}</ref>
	Additionally, Gracenote operates a digital file identification service which allows digital music files to be identified. As well as a media management service for media management such as the generation of playlists, and recommendation of music.

			On September 9, 2010, Gracenote received its one-billionth piece of data, with a submission about the ] release of ]' '']''.<ref name="billion">{{cite news \|url=https://www.nytimes.com/2010/10/04/business/media/04link.html?_r=1&src=busln&pagewanted=all \|title=Obsessions With Minutiae Thrive as Databases \|last=Cohen \|first=Noam \|newspaper=] \|date=2010-10-03 \|access-date=2010-10-04}}</ref>
	Gracenote's database is mainly created via the contributions of its many users. If the music is not available in the Gracenote database, the service requests the user to input information such as the artist, album, and song names related to the music. Gracenote also receives some music information from third party database companies and record labels.

			On December 23, 2013, Sony announced it would sell Gracenote to ] for $170 million. The acquisition closed in February 2014: Gracenote was aligned with the ] division which focused on TV and Movie metadata and IDs.<ref name=variety-tribuneacquire>{{cite web\|title=Tribune Closes $170 Mil Cash Deal to Acquire Sony's Gracenote\|url=https://variety.com/2014/digital/news/tribune-closes-170-mil-deal-to-acquire-sonys-gracenote-1201084243/\|website=Variety\|access-date=31 January 2015}}</ref><ref name=wsj-tribgracenote>{{cite news\|title=Tribune Buys Gracenote From Sony\|url=https://www.wsj.com/articles/SB10001424052702304020704579276363168307266\|access-date=31 January 2015\|work=The Wall Street Journal}}</ref>
	==Background==

			On June 12, 2014, ] merged with Gracenote to form one company under the Gracenote name.<ref>{{cite web\|url=http://www.rapidtvnews.com/2014061234059/tribune-to-merge-media-services-into-gracenote-operations.html\|title=Tribune to merge Media Services into Gracenote operations\|author=Michelle Clancy\|work=Rapid TV News\|access-date=5 June 2015\|archive-date=3 April 2015\|archive-url=https://web.archive.org/web/20150403142205/http://www.rapidtvnews.com/2014061234059/tribune-to-merge-media-services-into-gracenote-operations.html\|url-status=dead}}</ref>
	Gracenote began in ] as an ] project involving a CD player program named xmcd. The xmcd player was developed by ] and had the ability to store and recognize CDs from a database. Xmcd users regularly sent additional CD information to Mr. Kan for inclusion in the database via email. By 1995, the database had become unwieldy and ], a friend of Mr. Kan, was recruited to build a server to store the CD information in a network database. Later, hosting facilities and an advertising business model were provided by an ex-pat Scot living in Texas, Graham Toal.

			On July 9, 2014, Tribune Media Company purchased What's-ON, a provider of TV data and advanced search offerings covering India and the Middle East for $27 million.<ref>{{Cite web\|url=https://techcrunch.com/2014/07/09/tribune-whats-on/\|title=Tribune Digital Ventures Acquires Indian Electronic Program Guide Provider What's On\|last=Lawler\|first=Ryan\|website=TechCrunch\|access-date=2016-04-06}}</ref>
	As CDs do not generally contain any digitally-encoded information about their contents (see ]), Kan developed software which identifies and looks up CDs based on TOC information stored at the beginning of each disc. A ], or Table of Contents, is a list of offsets corresponding to the start of each track on a CD. The matching is fuzzy and tolerates some variation in track offsets.

			On September 3, 2014, Gracenote acquired ], a Los Angeles{{En dash}}based provider of film and TV data and information. Baseline had previously been owned by the ] from 2006{{En dash}}2011 after which it was sold back to its original owners. This $50 million purchase deepened Gracenote's existing video datasets and added the Studio System database, a subscription-based resource for the Hollywood content creation and distribution communities, to its line-up of offerings.<ref>{{Cite web\|url=https://variety.com/2014/digital/news/tribune-medias-gracenote-acquires-baseline-for-50-million-cash-1201296710/\|title=Tribune Media's Gracenote Acquires Baseline for $50 Million Cash\|last=Spangler\|first=Todd\|website=Variety\|language=en-US\|access-date=2016-04-06}}</ref>
	Some computer users who have copied ] from their turntables onto ]s have been surprised to find their computers correctly displaying the titles and track listings when these ]s are played on their computer. This happens when a commercial ] is a ] version of an ], containing the same tracks in the same order. If the track offsets of the homemade CD match the track timings of the commercial ] to within a second, the CDDB database can identify the ] successfully.

			On October 2, 2014, Gracenote purchased Australia-based TV and movie data company HWW for $19 million US to expand its Asia Pacific presence and international offerings.<ref>{{Cite web\|url=https://venturebeat.com/2014/10/02/gracenote-targets-australia-with-19m-buy-up-of-tv-movie-data-provider-hww/\|title=Gracenote targets Australia with $19M buy-up of TV & movie data provider HWW\|website=VentureBeat\|access-date=2016-04-06}}</ref>
	==Commercialization and controversy==
	In ], the service was purchased by ], a consumer electronics manufacturer and operated as a business unit within the ] based company. CDDB was then spun out of Escient and then in July of 2000 renamed Gracenote (). The maneuver was and remains controversial, because the CDDB database was and remains to be built on the voluntary submission of CD track data by thousands of individual users. Initially, most of these were users of the xmcd CD player program. The xmcd program itself was an open-source, ] project, and many listing contributors assumed that the database was open-source as well due to the GPL notice on the cddb.com website's and . The website was modified in 1998 to state that the database is the .

			On May 28, 2015, Gracenote acquired Amsterdam-based Infostrada Sports and Halifax-based SportsDirect, providers of music, video and sports data.<ref>{{Cite web\|url=https://www.multichannel.com/news/gracenote-puts-54m-two-sports-data-firms-390926\|title=Gracenote Puts Up $54M for Two Sports Data Firms\|website=www.multichannel.com\|access-date=2019-08-25}}</ref>
	], Gracenote claims that its database contains information on almost 4 million CDs. The reliability both of this statement and of the database itself have been challenged. Because the information going into the database has not been subjected to quality control, duplicate entries are very common. David Jennings, in an article entitled "How many CDs are there in the world?" gives an example of a six-CD set in which "two of the six CDs appear twice in the database, and one appears three times" () An article on the Seattle Times website cites Ty Roberts, chief technology officer of Gracenote, as saying that there are approximately 500,000 individual CD titles commercially released and available for sale today in the United States.<ref>{{cite news

	===Gracenote v. Musicmatch===

			After divestiture of ] (the former ACNielsen consumer research business) in 2021, Nielsen became solely a media audience measurement and analytics firm including Gracenote.<ref>{{Cite web \|last=Lafayette \|first=Jon \|date=2021-03-05 \|title=Nielsen Completes $2.7 Billion Sale of Global Connect Business \|url=https://www.nexttv.com/news/nielsen-completes-dollar27-billion-sale-of-global-connect-business \|access-date=2024-08-29 \|website=] \|language=en}}</ref><ref name=":0">{{Cite web \|last=Lafayette \|first=Jon \|date=2022-10-11 \|title=Nielsen Completes $16 Billion Sale to Private Equity Consortium \|url=https://www.nexttv.com/news/nielsen-completes-dollar16-billion-sale-to-private-equity-consortium \|access-date=2024-08-29 \|website=] \|language=en}}</ref>
	In ], Gracenote sued another former licensee, ], for breach of contract and patent violations. Musicmatch filed a counter-suit against Gracenote. The Northern District Court in California ruled on ], ] in favor of Musicmatch. The case was settled in ] after Musicmatch received summary judgement on all of Gracenote's patent claims.

			In October 2022, Nielsen and its subsidiaries (including Gracenote) were purchased by a private equity consortium led by affiliates of ] and ] in an all-cash transaction valued at approximately $16 billion, including the assumption of debt.<ref name=":0" />
	A summary judgement found that Musicmatch's CDDB replacement service does not violate Gracenote's patents. The court also found significant evidence that Gracenote may have obtained its patents fraudulently. is available online. Later, the court issued a decision that Gracenote did not obtain its patents fraudulently, but the decision that Musicmatch does not violate any of Gracenote's patents was clear.

	There has been speculation that Yahoo! had been holding off its decision to purchase Musicmatch for nearly seven months until the August 26th court order was issued. According to this speculation, the court decision for Yahoo!'s purchase of Musicmatch. The purchase of Musicmatch by Yahoo! was announced only two weeks after the August 26th court decision. Musicmatch and Gracenote settled shortly thereafter.

			Gracenote is known for MusicID, a music recognition software which identifies compact discs and delivers artist metadata and cover art to the desktop. The Gracenote database includes music genre and mood information, TV show descriptions, episode information, and channel line-ups, movie cast and crew information, and sports statistics and results. Companies including music services, TV providers, consumer electronics manufacturers and automakers use Gracenote data to power their content, universal search, navigation, linking, discovery and personalized recommendations abilities.{{cn\|date=March 2020}}

			Gracenote's music recognition technologies compare digital music files to a worldwide database of music information, enabling digital audio devices to identify songs. The company licenses its technologies to developers of consumer electronics devices and online media players, who integrate the technologies into media players, home and car stereos, and digital music devices.<ref name="Hoovers">{{cite web\|url=http://www.hoovers.com/company-information/cs/company-profile.gracenote_inc.7f295723145ef70e.html\|title=Gracenote, Inc.

	Until the Musicmatch case, Gracenote attempted to aggressively use its patents in an attempt to enforce a monopoly in commercial CD indentification services. The inability of Gracenote to enforce its patent in the Musicmatch case opened the market for competition, and a growing global group of companies continue to enter media identification and metadata marketplace.

			It provides software and ] to businesses which enables their customers to manage and search digital media. Gracenote provides its media management technology and global media database of ] information to the ], automobile, ], home, and ] markets. Several software applications which were capable of playing CDs (e.g. ] and ],) used Gracenote's ] technology. ], once a major licensee, no longer has access to Gracenote; the legacy media player program lost access to Gracenote when ] and Winamp were sold by AOL in 2014.<ref>{{Cite web\|url=http://forums.winamp.com/showpost.php?p=2995107&postcount=2\|website=Winamp & SHOUTcast Forums \|title=CDDB problems (Gracenote Services No Longer Work In Winamp: Reason Why Explained)\|access-date=2017-01-12}}</ref> Redevelopment of Winamp continues by its new owner ] who have said future Winamp versions will have access to an online music database.<ref>Winamp Official Forum</ref>{{nonspecific\|date=January 2023}}

	==Competition==

			With the acquisition by Tribune Media in 2014 and subsequent acquisitions of What's-ON, HWW, Baseline, SportsDirect, and Infostrada Sports, Gracenote has expanded its core data product beyond music into video and sports.
	After the commercialization of Gracenote a few other music databases started up such as ], ], ], and ].

			Gracenote's early product line-up consisted of MusicID, Mobile MusicID, Music Enrichment, Discover, Playlist, Playlist Plus, Media VOCS, Classical Music Initiative, and Link.

			Gracenote's current Music offerings fall into three major categories: Music Recognition, Music Data, and Music Discovery. Its music recognition product called MusicID was originally developed as a CD track-identification system. Gracenote also operates a digital file identification service that uses audio fingerprinting technology to identify digital music files such as MP3s and deliver track-level metadata, album art, and links to complementary content and services.

	'''Slashdot''' (often abbreviated as '''/.''') is a technology-related news ] which features user-submitted and editor-evaluated ] news with a ]y slant. It is known for the ]-style comments section attached to each story; Slashdot was one of the first popular websites to include a commentary section in such a prominent manner. The site slogan is ''"News for nerds. Stuff that matters."''

			Gracenote's video platform called On Entertainment consists of TV listings and schedules for approximately 85 countries and 35 languages as well as TV and Movie data and related-imagery information for six million TV shows and movies. On Entertainment is supported by standardized TMS IDs for TV shows, movies, and celebrities. These IDs enable universal search across linear TV, OTT and VOD libraries and make possible "season pass" DVR recordings.{{cn\|date=March 2020}}
	The summaries for the stories are generally submitted by Slashdot's own readers with editors accepting or rejecting these contributions for general posting. While Slashdot's haphazard ] produced a unique voice in the pre-blog age, users frequently post criticisms of perceived arbitrariness or bias in editorial choices.

			Gracenote Sports provides live scores, play-by-play data, historical results and records, schedules, player profiles, and athlete biographies for 4,500 leagues and competitions such as the NFL, MLB, NBA, NHL, Premier League, F1, Bundesliga, Tour de France, Wimbledon, and the Olympics. Gracenote's Podium product tracks all Olympic competition results and rankings at elite and junior levels as well as historical Olympic data going back to the very first modern games in 1896. In September 2015, the company announced DVR Extend which enables TV providers to dynamically adjust DVR settings to ensure live sports game recordings do not get cut off in the event they go past scheduled broadcast times.<ref>{{Cite web\|url=http://www.twice.com/news/video/gracenote-dvrs-extend-record-time-if-sports-game-goes-overtime/58537\|title=Gracenote: DVRs To Extend Record Time If Sports Game Goes Into Overtime\|website=www.twice.com\|access-date=2016-04-06}}</ref>
	Though the site antedates the modern concept of the ], Slashdot's architecture is commonly compared to that of modern blogs.

For instance, any programs using a CDDB lookup had to display a CDDB logo while performing the lookup. Then, in March 2001, only licensed applications were provided access to the Gracenote database. New licenses for CDDB1 (the original version of CDDB) were no longer available, so programmers using Gracenote services were required to switch to CDDB2 (a new version incompatible with CDDB1).
	The software that runs Slashdot is called ], and is available under the terms of the ].

			This has been controversial, as the original CDDB database was created out of anonymous contributions, initially via the ] xmcd CD player program. Many listing contributors believed that the database was open-source as well because, in 1997, cddb.com's download and support pages had said it was released under the GPL. CDDB claims that the license grant was an error.

			* ]
	]
			* ]
	To prevent abusive comments, a ] has been implemented whereby every comment posted (including those posted anonymously) can be "moderated" up or down by ], changing the post's score likewise. Moderation points added to a comment are also added to a user's karma score. Having high karma gives added bonuses to users, such as the ability to autopost at higher starting values. Conversely, users with low karma have penalties imposed on them. People that post comments designed to get more karma, for example mirroring a linked article or presenting a banal groupthink opinion or lame joke, are referred to as karma whores. Those who can moderate are selected by their karma score and number of meta moderations (and maybe other criteria). Slashdot editors, including ] ("CmdrTaco"), can moderate limitlessly. Moderator access for non-editors is time limited (to a few days) and the number of 'mod points' one gets is limited to a total of +5 points.

	A given comment can have any integer score from −1 to +5, and Slashdot users can set a personal threshold where no comments with a lesser score are displayed. A person browsing the comments at a threshold of 1 will not see comments with a score of −1 or 0 but will see all others. A ] was implemented to moderate the moderators and help contain abuses.

	==Slashdotting==
	{{Main\|Slashdot effect}}
	Historically, sites that received a mention on Slashdot could get "Slashdotted" if the flood of attention that the link generated overwhelmed their servers. This is similar to a website being "]", a recent term coined when a site is overwhelmed because of a link on Digg. The effect for the webmaster of the linked site is often the same, with their servers being unable to keep up with the short term demand.

	The demand on the servers is reduced as the Slashdot story is moved down or off the front page from new stories being posted. Some webmasters have responded (either before or during a Slashdotting) by replacing dynamic content with static content on that page, to reduce the load and allow their servers to handle more requests. Rarely, a webmaster will take the entire page down or replace it with a blank page temporarily if the traffic is not wanted. Today, most major websites can handle the surge of traffic and Slashdotting usually occurs only on smaller or independent sites.

	==Article sections==
	As of ] ], Slashdot articles are divided into the following sections:<ref>{{ cite web \| url = http://slashdot.org/faq/editorial.shtml \| title = Slashdot FAQ: What are the Slashdot Sections for? \| publisher = Slashdot.org }}</ref>

	* • Articles related to products from ], such as ], ], as well as items that directly compete with those products.
	* • Articles that seek advice from the Slashdot readership about jobs, computer hardware, software glitches, philosophical problems, etc.
	* Backslash • This section contains editor's picks of best comments from a recent popular article, primarily intended for those who do not want to read hundreds of high-moderated comments from the original thread.
	* • This section is for original book reviews on (not necessarily) tech books.
	* • News about the software, or anything that directly affects the practice of programming. (i.e. A new programming language? A useful technique? Licensing issues?)
	* Entertainment
	* Games
	* Hardware
	* • This is the place to suggest possible Slashdot interviewees (with contact information, if possible, and background material.)
	* Information Technology () • Anything that people with "Information Technology" in their job description might be interested to know.
	* • The Linux section is for news specific to ]
	* News
	* • This section is for news relevant to United States government politics. It was created primarily to cover the 2004 US Presidential Election, but now exists for occasional stories that are related to U.S. Politics.
	* • This is the place for science articles. Cool technology, space telescope observations, interesting medical research.
	* Technology
	* Your Rights Online () • News affecting your ability to live as a free, responsible person online. Such examples are Spam, invasions of privacy, and onerous licenses.

	The section is still posted to, although it no longer enjoys a place in the main site navigation. The section was a web audio broadcast featuring several of the editors of Slashdot; there have been no recent updates to this section.

	==Site Growth==

	Speculation abounds on whether Slashdot continues to grow in popularity or is actually declining. Actual traffic numbers are disclosed in quarterly profit releases and concomitant conference calls by parent company ]. These traffic numbers cover the ] as a whole, which notably includes ] traffic as well as Slashdot. Traffic for the quarter ended October 31, 2006 was 32 million unique visitors and 1.5 billion page views. This represents about 50% growth year over year, from 22 million unique visitors and 1 billion page views. It also represents a sequential increase from the previous quarter, which reported 30 million unique visitors and 1.2 billion page views.

	As of early October 2006, ] shows a slight decrease in queries including the word "slashdot" over the past year<ref name="trends">http://www.google.com/trends?q=slashdot%2Cdigg%2Creddit&ctab=0&geo=all&date=all</ref>, suggestive of a concomitant drop in relative traffic. Google Trends shows the popularity of a query relative the total number of search queries, and thus no absolute trends can be derived from the Google Trends graph.

	Web analysis site ] shows that the number of visitors to Slashdot as well as the relative popularity of the site shot up in 2006, peaking in May 2006. The Alexa rankings, however, are not to be considered accurate, as one of the webmasters for Slashdot has said that the sudden jump in Alexa ranking was not at all consistent in actual server load - the ranking jumped but the number of actual page views remained steady.

	==Criticism==
	Critics claim that the quality of materials found on Slashdot has progressively declined. Common complaints include:

	*The frequency of reposts (also known as "dupes"), where editors approve articles for the front page, often slightly reworded, that have previously appeared on the site. Since the major responsibility of editors is to sift through article submissions, reposts leave the impression of incompetence. Some readers have called for mandatory procedures to search for Slashdot dupes before an article is published<ref> - At that day, complaints about Slashdot story selection process were appearing on all published stories, which prompted a response from Slashdot editors</ref>.

	*Some article summaries have typos, misleading titles, or errors. An example of this is an article titled '''"Spain Outlaws P2P File Sharing"''' where the article summary states that Spain is banning all ] file sharing, a huge fuss ensues in the discussion, while the reality is that Spain only made it a civil offence to pirate movies, which is hardly "Outlawing P2P".

	==Culture==
	{{unreferenced\|\|date=June 2006}}

	As Slashdot has existed for so many years, it has developed its own subculture, especially running jokes and gags. Among these include:
	* ]
	* ]
	* "Hot Grits" Troll
	* ]...
	* "Imagine a ] cluster of those"
	* "But does it run Linux?" trolls and other Slashdot trolling phenomena
	* ]
	* I ''<cite silly personal offence>'', you !
	* 1) ''<some action>'' 2) ... 3) Profit!!!

	Additionally, the ID of the Slashdot user is sometimes regarded as a sign of how ] the user is, although this is not taken very literally. Having a user ID that is a ] or other significant mathematical number is also valued. Some people have successfully sold their Slashdot ID (usually because it was a low 4 digit or smaller), although the website's policy on this isn't exactly clear. Slashdot assigns user ID numbers in the order that the user registered, so the lower the user ID, the longer they have been a registered user, and thus (implicitly) the more experienced they are in the computer field.

	===Audience===
	While Slashdot's core audience is often said to consist of ] enthusiasts and various other enthusiasts of the ] software movement, there is a significant Windows audience as well. A poll on Slashdot suggests that approximately half of all Slashdot visitors use ] as their ], a third use some form of Linux, and above ten percent use ]. But what is probably significant is the number of cross-users, that is people who use more than one if not all the mentioned systems.<ref> (2002)</ref> Polls on Slashdot, like most on the Internet, may be unreliable. The ongoing assumption that Slashdot is Linux-oriented comes both from historical reasons and from its famous ] "]" icon.{{or}} Despite this reputation, many Slashdot stories are related to Windows ]s or applications, or Microsoft security bulletins.{{cn}}

	Famous or well-known active "Slashdotters" include ] co-founder ] (username ""), actor ] (username ""), ] technical director ] (username ""), ] author ] (username ""), ] and ] architect Miguel de Icaza (username ""), ] creator ] (username ""), ] creator ] (username ""), and ] evangelist ] (username ""). Several engineers from NASA involved in the ] rover exploration projects have participated.{{cn}}

	===Trolling===

	As one of the largest forums on the Internet, ] and ] on Slashdot is a highly evolved phenomenon. It is an offbeat and complex subculture involving sometimes repetitive and sometimes obscene comments featuring a mixture of Slashdot celebrities and other unusual juvenilia.

	The Slashdot editors are sometimes accused of posting (and even preferring) stories that are, themselves, thinly-disguised trolls, which encourage large numbers of postings in response.

Gracenote, Inc. is a company and service that provides music, video, and sports metadata and automatic content recognition (ACR) technologies to entertainment services and companies worldwide. Formerly CDDB ("Compact Disc Data Base"), Gracenote maintains and licenses an Internet-accessible database containing information about the contents of audio compact discs and vinyl records. From 2008 to 2014, it was owned by Sony, later sold to Tribune Media, and has been owned since 2017 by Nielsen Holdings. In 2019, Nielsen Holdings announced plans to split into two separate publicly traded companies, Nielsen Global Connect (later known as NielsenIQ and sold) and Nielsen Global Media. In October 2022, Nielsen Holdings (by then consisting of the Global Media business), including the Gracenote subsidiary was acquired by a private equity consortium.

History

Gracenote began in 1993 as an open-source project involving a CD player program named xmcd and an associated database named CDDB. xmcd and CDDB were created by Ti Kan and Steve Scherf. Because CDs do not contain any digitally-encoded information about their contents, Kan and Scherf devised a technology that identifies and looks up CDs based on TOC information stored at the beginning of each disc. A TOC, or Table of Contents, is a list of offsets corresponding to the start of each track on a CD. Its original database was created from and continues to receive voluntary contributions from users. This led to a licensing controversy when Gracenote became commercialized.

On April 22, 2008, Sony announced that it would acquire Gracenote for $260 million. The acquisition was completed on June 2, 2008.

On September 9, 2010, Gracenote received its one-billionth piece of data, with a submission about the Compact Disc release of Swans' My Father Will Guide Me Up a Rope to the Sky.

On December 23, 2013, Sony announced it would sell Gracenote to Tribune Media for $170 million. The acquisition closed in February 2014: Gracenote was aligned with the Tribune Media Services division which focused on TV and Movie metadata and IDs.

On June 12, 2014, Tribune Media Services merged with Gracenote to form one company under the Gracenote name.

On July 9, 2014, Tribune Media Company purchased What's-ON, a provider of TV data and advanced search offerings covering India and the Middle East for $27 million.

On September 3, 2014, Gracenote acquired Baseline, a Los Angeles–based provider of film and TV data and information. Baseline had previously been owned by the NY Times from 2006–2011 after which it was sold back to its original owners. This $50 million purchase deepened Gracenote's existing video datasets and added the Studio System database, a subscription-based resource for the Hollywood content creation and distribution communities, to its line-up of offerings.

On October 2, 2014, Gracenote purchased Australia-based TV and movie data company HWW for $19 million US to expand its Asia Pacific presence and international offerings.

On May 28, 2015, Gracenote acquired Amsterdam-based Infostrada Sports and Halifax-based SportsDirect, providers of music, video and sports data.

On December 20, 2016, Tribune Media announced that it was selling Gracenote to Nielsen Holdings for $540 million in cash. The deal officially closed on February 1, 2017. In September 2017, Gracenote partnered with Connekt and Ensequence to deliver real-time offers on smart TVs.

On November 7, 2019, Nielsen announced that it was splitting into two separate publicly traded companies. Gracenote fell under the company's Global Media business.

After divestiture of NielsenIQ (the former ACNielsen consumer research business) in 2021, Nielsen became solely a media audience measurement and analytics firm including Gracenote.

In October 2022, Nielsen and its subsidiaries (including Gracenote) were purchased by a private equity consortium led by affiliates of Elliott Investment Management and Brookfield Business Partners in an all-cash transaction valued at approximately $16 billion, including the assumption of debt.

Gracenote is known for MusicID, a music recognition software which identifies compact discs and delivers artist metadata and cover art to the desktop. The Gracenote database includes music genre and mood information, TV show descriptions, episode information, and channel line-ups, movie cast and crew information, and sports statistics and results. Companies including music services, TV providers, consumer electronics manufacturers and automakers use Gracenote data to power their content, universal search, navigation, linking, discovery and personalized recommendations abilities.

Gracenote's music recognition technologies compare digital music files to a worldwide database of music information, enabling digital audio devices to identify songs. The company licenses its technologies to developers of consumer electronics devices and online media players, who integrate the technologies into media players, home and car stereos, and digital music devices.

It provides software and metadata to businesses which enables their customers to manage and search digital media. Gracenote provides its media management technology and global media database of digital entertainment information to the mobile, automobile, portable, home, and PC markets. Several software applications which were capable of playing CDs (e.g. Media Go and iTunes,) used Gracenote's CDDB technology. Winamp, once a major licensee, no longer has access to Gracenote; the legacy media player program lost access to Gracenote when SHOUTcast and Winamp were sold by AOL in 2014. Redevelopment of Winamp continues by its new owner Radionomy who have said future Winamp versions will have access to an online music database.

In 2014 Tribune Media Company bought Gracenote from Sony Corporation of America. In December 2016, Tribune announced that it had reached an agreement to sell Gracenote to Nielsen Holdings for $560 million. The purchase was completed on February 1, 2017.

With the acquisition by Tribune Media in 2014 and subsequent acquisitions of What's-ON, HWW, Baseline, SportsDirect, and Infostrada Sports, Gracenote has expanded its core data product beyond music into video and sports.

Gracenote's early product line-up consisted of MusicID, Mobile MusicID, Music Enrichment, Discover, Playlist, Playlist Plus, Media VOCS, Classical Music Initiative, and Link. In April 2007, Gracenote launched the first legal lyrics offering in the U.S. that was sold to LyricFind in 2013.

Gracenote's current Music offerings fall into three major categories: Music Recognition, Music Data, and Music Discovery. Its music recognition product called MusicID was originally developed as a CD track-identification system. Gracenote also operates a digital file identification service that uses audio fingerprinting technology to identify digital music files such as MP3s and deliver track-level metadata, album art, and links to complementary content and services. Its music data offering provides information describing Genre, Mood, Era, Origin and Tempo for tens of millions of songs.

Gracenote Auto puts Automatic Content Recognition (ACR) technology into the car's audio system to identify music playing from various sources including AM/FM and satellite radio, CDs or streaming services and deliver relevant metadata and cover art. In December 2015, Gracenote launched its first audio technology, Gracenote Dynamic EQ, designed to help automakers and OEMs automatically tune connected car audio systems to the optimal equalizer settings for individual songs based on genre, mood and release date.

Gracenote's video platform called On Entertainment consists of TV listings and schedules for approximately 85 countries and 35 languages as well as TV and Movie data and related-imagery information for six million TV shows and movies. On Entertainment is supported by standardized TMS IDs for TV shows, movies, and celebrities. These IDs enable universal search across linear TV, OTT and VOD libraries and make possible "season pass" DVR recordings.

Gracenote Sports provides live scores, play-by-play data, historical results and records, schedules, player profiles, and athlete biographies for 4,500 leagues and competitions such as the NFL, MLB, NBA, NHL, Premier League, F1, Bundesliga, Tour de France, Wimbledon, and the Olympics. Gracenote's Podium product tracks all Olympic competition results and rankings at elite and junior levels as well as historical Olympic data going back to the very first modern games in 1896. In September 2015, the company announced DVR Extend which enables TV providers to dynamically adjust DVR settings to ensure live sports game recordings do not get cut off in the event they go past scheduled broadcast times.

Customers

iTunes, Media Go, Sonicstage, Groove Music and Windows Media Player all use or have used Gracenote's CD track identification services. In addition, Gracenote provides or provided its products to a number of other services including online services like Yahoo! Music Jukebox, AOL, AmazonMP3, Spotify, Winamp, MetroLyrics, Pandora, Google Music;, home and automotive products such as those from Alpine, Bose, or Panasonic; mobile music applications from Samsung and others, Sony Mobile Communication (TrackID, Sony Movies/Video & TV SideView App for Xperia Through Gracenote Video Explore and Sony Music Walkman App for Xperia), and the ACR technology into the car audio systems for Tesla, BMW, Nissan and several other car makers.

Controversy

Main article: Gracenote licensing controversy

In 1998, CDDB was purchased by Escient, a consumer electronics manufacturer, and operated as a business unit within the American company. CDDB was then spun out of Escient and in July 2000 was renamed Gracenote. The CDDB database license was later changed to include new terms. For instance, any programs using a CDDB lookup had to display a CDDB logo while performing the lookup. Then, in March 2001, only licensed applications were provided access to the Gracenote database. New licenses for CDDB1 (the original version of CDDB) were no longer available, so programmers using Gracenote services were required to switch to CDDB2 (a new version incompatible with CDDB1).

This has been controversial, as the original CDDB database was created out of anonymous contributions, initially via the open source xmcd CD player program. Many listing contributors believed that the database was open-source as well because, in 1997, cddb.com's download and support pages had said it was released under the GPL. CDDB claims that the license grant was an error.
