In 2006, Viacom acquired Harmonix, a video game studio oriented towards music video games and the original developer of the Guitar Hero franchise, for $175 million. The two subsequently collaborated on the creation of Rock Band. That year, Viacom also acquired the gaming-oriented communications platform Xfire.
In 2010, Harmonix was divested to an investment firm to become an independent studio, and Xfire was sold.
In 2011, Viacom established a new in-house studio known as 345 Games, which is dedicated primarily to developing games based on Comedy Central and MTV properties.
