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
"Guitar Hero" was created from a partnership between RedOctane, then their own company that produced specialized video game controllers, and Harmonix, a music video game development company who had previously produced "Frequency", "Amplitude" and "Karaoke Revolution". RedOctane was seeking to bring in a "Guitar Freaks"-like game, highly popular in Japan at the time, into Western markets, and approached Harmonix about helping them to develop a music game involving a guitar controller. Both companies agreed to it, and went on to produce "Guitar Hero" in 2005. The title was highly successful, leading to the development of its successful sequel "Guitar Hero II" in 2006. While the original controllers for the first "Guitar Hero" game were designed by Ryan Lesser, Rob Kay, Greg LoPiccolo and Alex Rigopulous of Harmonix and built by the Honeybee Corporation of China, subsequent iterations and future controllers were developed inhouse at RedOctane, with development led primarily by Jack McCauley.
