The Pulse of Radio is reporting that Guitar Hero III grossed more than $100 million in its first seven days on sale in North America, according to Variety.com. Activision revealed the figures on Monday (November 5th), making the music-based video game the second biggest title of the year after Halo 3, which hauled in $170 million in its first day alone. The sales of Guitar Hero could be either a positive or negative sign for the upcoming Rock Band, depending on how much money players have left to spend when the latter game arrives at the end of the month.

The third entry in the massively popular Guitar Hero series, which has been promoted by commercials featuring VELVET REVOLVER guitarist Slash (ex-GUNS N' ROSES), features songs from DISTURBED, SLIPKNOT, THE KILLERS, AEROSMITH, A.F.I., GUNS N' ROSES, METALLICA, MUSE, PEARL JAM, RAGE AGAINST THE MACHINE, RED HOT CHILI PEPPERS, SMASHING PUMPKINS and dozens more.
