It's official... "Guitar Hero" has become a full-fledged, bonafide cultural phenomenon! Topping 15 million units sold, the video game has generated some $1 billion in sales, and shows no signs of slowing. Competitions at bars have become widespread, and new versions featuring the music of Aerosmith and perhaps even Rush are on the way. For more info www.guitarhero.com.

New on the scene is the even more amazing "Rock Band" video game. Played with not just a single guitar-shaped controller but with guitar, bass, drums and vocals, this game is a cross between Guitar Hero and karaoke. In essence, you and your friends can all jam together! The company recently brought a demo version to one of my "Friday Night Live" broadcasts. To say it was a huge hit was an understatement.
