The Entertainment Software Association announced today the results of data gathered by the NPD Group. The report shows that “Family Entertainment” game sales grew by 110% in 2007. The best selling game title of the year was Halo 3.

"The video game industry set the pace over all others in 2007, with record-breaking sales, off-the-charts consumer demand, and innovation reaching from galactic exploration to guitar simulation," said Michael D. Gallagher, president and CEO of the ESA, the U.S. association representing computer and video game software publishers. "On average, an astonishing 9 games were sold every second of every day of the year."

The study data shows that more than 13.4 million portable game units were sold in 2007. Only 15.5% of the games sold last year carry the Mature rating while a full 56.5% of the games sold had an E10+ rating. Teen rated games accounted for 28% of the games.
