One of the biggest pieces of news to come out of this year's Consumer Electronics Shows: Guitar Hero III is now the best-selling videogame of all time, racking up more than $1 billion - yes, billion - in sales. And that's just in the game's first year.
Why the success? Because the developers of Guitar Hero didn't just create a videogame, they developed a new way to experience and receive music. About a year ago, I met with the two MIT media lab grads who created the franchise - really interesting guys who set out not just to make a game, but to reinvent how music is distributed and consumed in the digital age. They've since split off to do the Rock Band franchise, and are working on the first ever Beatles videogame - due later this year.
