The PlayStation ((Japanese: プレイステーション) is a video game console of the 32/64-bit era, first produced by Sony Computer Entertainment in the mid-1990s. The original PlayStation was the first of the PlayStation series of console and hand-held game devices, which has included successor machines including the Net Yaroze, PSOne (a smaller version of the original), PocketStation, PlayStation 2, PlayStation Portable, PSX (Japan only), and the forthcoming PlayStation 3.

By March 2005, the PlayStation/PSone had sold a total of over 100.49 million units , becoming the first home console to ever reach the 100 million mark. In 2001, Sony advertised in a press release that one in three houses in the US owned a PlayStation .

History

Development

The first conceptions of the PlayStation console date back to 1986. Nintendo had been attempting to work with disk technology since the Famicom, but the medium had problems. Its rewritable magnetic nature could be easily erased (thus leading to a lack of durability), and the disks were a piracy danger. Consequently, when details of CDROM/XA (an extension of the CD-ROM format that combines compressed audio, visual and computer data, allowing all to be accessed simultaneously) came out, Nintendo was interested. CDROM/XA was being simultaneously developed by Sony and Philips. Nintendo approached Sony to develop a CD-ROM add-on, tentatively titled the "SNES-CD". A contract was struck, and work began. Nintendo's choice of Sony was due to a prior dealing: Ken Kutaragi, the person who would later be dubbed "The Father of PlayStation," was the individual who had sold Nintendo on using the Sony SPC-700 processor for use as the 8 channel ADPCM sound synthesis set in the Super Famicom/SNES console through an impressive demonstration of the processor's capabilities.

Sony also planned to develop another, Nintendo compatible, Sony-branded console, but one which would be more of a home entertainment system playing both Super Nintendo cartridges and a new CD format which Sony would design. This was also to be the format used in SNES-CD discs, giving a large degree of control to Sony despite Nintendo's leading position in the video gaming market.

In 1991, the SNES-CD was to be announced at the June CES. However, when Hiroshi Yamauchi read the original 1988 contract between Sony and Nintendo, he was furious. He deemed the contract totally unacceptable, and secretly cancelled all plans for a joint Nintendo-Sony SNES CD attachment. Indeed, instead of announcing their partnership, at 9 am the day of the CES, Nintendo chairman Howard Lincoln stepped onto the stage and revealed that they were now allied with Philips, and were planning on abandoning all the previous work Nintendo and Sony had accomplished. Lincoln and Minoru Arakawa had (unbeknownst to Sony) flown to Philips headquarters in Europe and formed an alliance of a decidedly different nature—one that would give Nintendo total control over its licenses on Philips machines.

The 9am CES announcement was a huge shock. Not only was it a complete surprise to the showgoers (Sony had only just the previous night been optimistically showing off the joint project under the "Play Station" brand), but it was seen by many in the Japanese community as a massive betrayal: a Japanese company snubbing another Japan-based company in favor of a European one was considered unthinkable in Japanese business.

After the collapse of the joint project, Sony considered halting their research, but ultimately the company decided to use what they had developed so far and make it into a complete, stand alone console. This led to Nintendo filing a lawsuit claiming breach of contract and attempted, in U.S. federal court, to obtain an injunction against the release of the Play Station, on the grounds that Nintendo owned the name. The federal judge presiding over the case denied the injunction. Thus, in October 1991, the first incarnation of the new Sony PlayStation was revealed; it's estimated that only 200 or so of these machines were ever produced.

By the end of 1992, Sony and Nintendo reached a deal whereby the "Sony Play Station" would still have a port for SNES games, but Nintendo would own the rights and receive the bulk of the profits from the games, and the SNES would continue to use the Sony-designed audio chip. However, at this point, Sony realised that the SNES technology was getting long in the tooth, and the next generation of console gaming was around the corner: work began in early 1993 on reworking the "Play Station" concept to target a new generation of hardware and software; as part of this process the SNES cartridge port was dropped, the space between the names was erased, and the PlayStation was born.

Launch

The PlayStation was launched in Japan on December 3, 1994, the USA on September 9, 1995 and Europe on September 29, 1995. In America, Sony enjoyed a very successful launch with titles of almost every genre including Toshinden, Twisted Metal, Warhawk, Philosoma, Wipeout and Ridge Racer. Almost all of Sony's and Namco's launch titles went on to produce numerous sequels.

Launch price in the American market: US$ 299.00 , a price later repeated by its successor.

The PlayStation was also able to generate interest with a unique slew of ad campaigns. Many of the ads released at the time of launch were full of ambiguous content which had many gamers rabidly debating their meanings. The most well-known launch ads include the "Enos Lives" campaign, and the "You Are Not E" ads (the "E" in "You Are Not E" was always colored in red, to symbolize the word "ready", and the "Enos" meant "ready Ninth Of September", the U.S. launch date). It is believed that these ads were an attempt to play off the gaming public's suspicion towards Sony as an unknown, untested entity in the video game market.

Titles

The console was extremely popular, spawning the so-called "PlayStation Generation". Well known titles on the PlayStation include Tomb Raider, Final Fantasy VII, Resident Evil, Tekken, Wipeout, Gran Turismo, Crash Bandicoot, Spyro The Dragon, Parasite Eve, Silent Hill, and Metal Gear Solid. As of May 18 2004, Sony has shipped 100 million PlayStation and PSone consoles throughout the world. As of March 2005, there were 7,743 software titles available (this figure counts games released in multiple regions as separate titles) with cumulative software shipment of 959 million. The PlayStation logo was designed by Manabu Sakamoto, who also designed the logo for Sony's VAIO computer products.

Production run

Having lasted over 11 years, the PlayStation has enjoyed one of the longest production runs in the videogame industry. On March 23, 2006, Sony announced the end of production.

Variants

The first new version was actually a revision in early 1996, produced in response to complaints that PlayStations were overheating. Sony did not change the technical aspects or the cosmetics but did remove the RCA ports left over from the Japanese release. The parallel port (which was mostly unused by Sony) was also removed to reduce production costs. Sony also slightly improved the laser assembly.

Many gamers experienced skipping full-motion video or dreaded physical "ticking" noises coming from their PlayStations. The problem appears to have come from poorly placed vents leading to overheating in some environments — the plastic moldings inside the console would warp very slightly and create knock-on effects with the laser assembly. The solution was to ensure the console was sat on a surface which dissipated heat efficiently in a well vented area, or raise the unit up slightly by propping something at its edges. A common fix for already affected consoles was to turn the PlayStation sideways or upside-down (thereby using gravity to cancel the effects of the warped interior) although some gamers smacked the lid of the PlayStation to make a game load or work.

This problem was carried over to many first-generation PlayStation 2s in the form of the very well known Disc Read Error message. However the PS2's problem is unlikely to have been caused by overheating — rather, it is rumoured to have been due to the short working life of some laser units employed in early drives, coupled with the PS2's tendency to collect dust internally.

Sony then released a version dubbed "Dual Shock", which included a controller with 2 analog thumbsticks and a built in force-feedback feature.

Another version that was colored blue (as opposed to regular console units that were gray in color) was available to game developers and select press. Later versions of this were coloured green. Contrary to popular belief, the RAM was not 4 megabytes but instead the standard 2 megabytes. The console included a CD-ROM emulator board connected to a PC. It was also able to run in-development games which lacked region coding (which would be rejected by a normal PlayStation as though they were pirated copies). A few of these units eventually appeared for sale through somewhat dubious channels at high prices.

A white version was also produced that had the ability to play VCDs.

The installation of a modchip allows the PlayStation's capabilities to be expanded. This allows unauthorized copies of games to be played, but it also allows the playing of games from other regions, such as PAL titles on a NTSC console. Since modchips allow playing games recorded on a regular CD-ROM, it created a wave of games developed without official Sony approval, using free GNU compiler tools.

Net Yaroze

A version of the PlayStation called the Net Yaroze was also produced. It was more expensive than the original PlayStation, coloured black instead of the usual gray, and most importantly, came with tools and instructions that allowed a user to be able to program PlayStation games and applications without the need for a full developer suite, which cost many times the amount of a PlayStation and was only available to approved video game developers. Naturally, the Net Yaroze lacked many of the features the full developer suite provided. Programmers were also limited by the 2 MB of total game space that Net Yaroze allowed. That means the entire game had to be crammed into the 2 MB of system RAM. The user couldn't officially make actual game discs. The amount of space may seem small, but games like Ridge Racer ran entirely from the system RAM (except for the streamed music tracks of course). It was unique in that it was the only officially retailed Sony PlayStation with no regional lockout; it would play games from any territory.

PSone

The PSone (also PSOne or PS one), launched in 2000, is Sony's smaller (and redesigned) version of its PlayStation video game console. The PSone is about one-third smaller than the original PlayStation (38mm × 193 mm × 144 mm versus 45 mm × 260 mm × 185 mm). It was released in September 2000, and went on to outsell all other consoles—including Sony's own brand-new PlayStation 2—throughout the remainder of the year. Sony also released a small LCD screen and an adaptor to power the unit for use in cars. The PSone is fully compatible with all PlayStation software. The PlayStation is now officially abbreviated as the "PS1" or "PSone," although many people still abbreviate it "PS" or "PSX". There were only 2 differences between the "PSone" and the original, the first one being cosmetic change to the console, and the second one was the home menu's Graphical User Interface. The PSOne also lacks the original PlayStation's serial port, which allowed multiple consoles to be hooked up for multi-TV multiplayer. The serial port could also be used for an external mod-chip, which may have been why it was removed, although size-constraints may also be to blame.

Summary of PlayStation models (to be completed)

(1) The x denotes region. European PAL has region "2", so units sold there where named for example SCPH-9002. NTSC countries (Japan and America) take region numbers "0", "1" and "3", thus all models ending in those numbers are NTSC models. (2) Button labels text "Power" and "Open" replaced with symbols

Successors

Sony's successor to the PlayStation is the PlayStation 2, which is backward compatible with its predecessor, in the sense that it can play almost every PlayStation game. This was done by embedding the most important parts of the PSone inside the PlayStation 2 design. Unlike emulators that run on the PC, the PlayStation 2 actually contains the original PlayStation processor, allowing games to run exactly as they do on the PlayStation. For PlayStation 2 games this processor, called the IOP, is used for input and output (memory cards, DVD drive, network, and hard drive). Like its predecessor, the PlayStation 2 is based on hardware developed by Sony themselves.

The next generation of the PlayStation is known as PlayStation 3, or PS3, and due to be launched in November 17 2006. Sony has stated the PS3 will also be backward compatible with all games that were originally made for PlayStation 1 as well as the PlayStation 2, and also will not be region-locked.

The PlayStation Portable (officially PSP) is a handheld game console first released in late 2004. Despite the name, it is not compatible with PlayStation games; it only runs games developed specifically for the PSP on the UMD format. However, at the PlayStation Briefing conference on March 15, 2006 in Japan, Sony revealed plans for PlayStation 1 games to be downloaded and playable on the PSP through emulation. Sony hopes to release nearly all PlayStation 1 games on a gradual basis.

The success of the PlayStation is widely thought to have had some influence on the demise of the cartridge-based home console. While not the first system to utilize an optical disc format, it was the first success story, and ended up going head-to-head with the last major home console to rely on proprietary cartridges - the Nintendo 64. Nintendo was very public about its skepticism toward using CDs and DVDs to store games, citing longer load times and durability issues. It was widely speculated that the company was even more concerned with piracy, given its substantial reliance on licensing and exclusive titles for its revenue. The success of Sony's PlayStation introduced high-quality sound and longer playing times as top priorities for modern gamers, leaving little choice for competitors but to follow suit.

Criticism

Advertising

To celebrate the ten-year anniversary of the Playstation in 2005, Sony Italy released an advertisement portraying a young man wearing a crown of thorns (the thorns being made of triangle, square, circle and x symbols, the labels on the buttons of Playstation controllers), on his head. The ad was captioned with "Dieci anni di passione" (In English, this translates to "Ten years of passion.")

The ad, assumed to be a takeoff of Mel Gibson's controversial 2004 movie The Passion of the Christ, was met with outrage from the Vatican. Sony apologized and stopped displaying the ad.

Quality of Construction

While the laser in the CD player usually worked, the plastic platform that held it rode on a set of rails; those rails eventually wore a groove into the plastic of the platform.

When the plastic wore down, the laser was no longer perfectly aligned with the surface of the CD. This meant games would take longer to load or not load at all.

If a game wouldn't load, a common fix involved standing the Playstation on its side. Since the Playstation was designed to sit flat, the laser platform wore down in the same way. By putting it on its side, the platform "hung" properly.

This was only a temporary fix, since the plastic on the platform would still wear out, just on a different side.

Many early adopters had to buy new Playstations, but Sony eventually fixed the problem by making the platform out of die-cast metal and hard plastic.

PlayStation as audio CD player

The PlayStation 1 has remarkable audio qualities. This was first observed by Keith Aschenbrenner of Auditorium 23, who used the Playstation as a source when demonstrating his Shindo systems. The first models of the PlayStation 1, in particular the SCPH 100x, perform on a level of music reproduction comparable to that of expensive high end audio equipment. Later models, the SCPH 500x up to SCPH 900x also perform well, but with increasing model type, the audio capabilities decrease. The PSOne and the PlayStation 2 are not suited for high-quality audio reproduction. The audio performance of the PlayStation 1 is good in the stock form, but it can be significantly increased by simple modifications of circuit and casing.
