In 2008, longtime flagship WTAM signed a five-year contract extension with the Cavaliers through the 2013–14 season; in 2011, a Cavs spokesman stated there were "multiple years" remaining on the team's contract with WTAM, without specifying an end date. In 2014, WTAM owner iHeartMedia (formerly Clear Channel) announced a new "multi-year" contract with the team; this new arrangement also established simulcasts on WTAM sister station WMMS. Additional affiliates were added in the Columbus, Dayton and Cincinnati markets, coinciding with LeBron James' heavily publicized return to the team.
John Michael took over as the team's lead play-by-play announcer starting in the 2011–12 season following the retirement of longtime radio voice Joe Tait. After the death of lead TV play-by-play announcer Fred McLeod prior to the start of the 2019–20 season, Michael was reassigned to that position, with Tim Alcorn—lead sports announcer and station manager at Cavaliers radio affiliate WEOL in Elyria—being hired as Michael's successor.
The radio network was rebranded as the "Cavaliers AudioVerse" beginning with the 2022–23 season.
