Activision became king of the hill in 2007 as the number one US publisher. According to NPD data the company's current market share is 17.7%, a 7.2% increase over last year. Of course, Activision utilized the powers it has as a third-party publisher to sell Guitar Hero III: Legends of Rock and Call of Duty 4: Modern Warfare,the number one and three titles in sales respectively, across multiple platforms. This is the first time in the company's history that it reached the top spot.

Activision was certainly on a financial and critical acclaim rampage in 2007. COD4 got a spot on our Top 10 list and GHIII was the number one game for our significant others. As successful as last year was, it's now looking like Rock Band is poised to make GHIII yesterday's news, which could be troubling for Activision considering how financially successful the Guitar Hero series has been. Then again, this year we'll start seeing the armed and fully-operational Blizzavision (yeah ... still working on that name).
