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 Superstar
Guitar Superstar is a yearly competition hosted by the Guitar Player magazine in which 10 finalists compete for the title of Guitar Superstar or Guitar Hero for the year. The competition started in 2005 as the Guitar Hero Competition but was changed in 2008 to the current title, probably to avoid confusion with the "Guitar Hero" video game series.
