Guitar Hero

In 2005, RedOctane, a company specializing in the manufacture of unique game controllers, was inspired to create Guitar Hero based on RedOctane's experience creating hardware for Konami's Guitar Freaks arcade game. They enlisted Harmonix, who previously developed several music video games, for development assistance. The first game in the series was made on a budget of $1 million. The series became extremely successful, leading to the acquisition of RedOctane by Activision in 2007. Harmonix was acquired by MTV Games and went on to create the Rock Band series of music games in the same vein as Guitar Hero. Activision brought Neversoft (primarily known for their Tony Hawk series of skateboarding games) on board for future development duties. Additional companies, such as Budcat Creations and Vicarious Visions have assisted in the adaptation of the games for other systems.
