Guitar Hero is the first console game franchise to surpass 1 million Facebook fans, says developer Activision.

As the number one best-selling third party video game franchise in America and Europe this year to date, since its release, more than 38 million games have been sold worldwide.

The most recent release "Guitar Hero 5" launched in September and is said to be the "most social and interactive Guitar Hero game ever".

The million-strong Facebook fans can get the latest info on Guitar Hero games and the artists in the games, as well as share their favourite artists, songs, and Guitar Hero experiences.
