Guitar Hero
In 2015, Activision announced the first new title to the series in 5 years, "Guitar Hero Live", released in October 2015. The title is considered a reboot of the series, with development being performed by FreeStyleGames, who had developed the "DJ Hero" games previously. As of December 1, 2018, Activision disabled the GHTV servers for Guitar Hero Live, reducing playable content from approximately 500 songs to 42 on disc tracks.
Guitar Hero
Prior to the release of "Guitar Hero III: Legends of Rock", Activision worked with the iTunes Store to provide more than 1300 tracks of "Guitar Hero"-related music across more than 20 compilations, including most of the tracks from the games in the series, called ""Guitar Hero Essentials"". These compilations, such as ""Killer Guitar Solos"" and ""Guitar Anthems of the '80s"", include songs related to but not contained within the "Guitar Hero" series. Dusty Welch of RedOctane stated, "Where there’s music, there’s "Guitar Hero", and with iTunes, we are able to provide fans with a central location for downloading their favorite rock anthems." Following the merger of Activision and Blizzard, the new company announced plans to create an alternative to iTunes based on the "Guitar Hero" brand that would allow for downloading songs and their associated note tracks for the "Guitar Hero" games.
