According to the Mobile Games report, the market for mobile games continues to expand quickly, with half of all U.S. wireless subscribers now owning phones capable of downloading games. A full 27 percent play games on those devices, including purchased downloads as well as free demos and pre-loaded games, compared to 20 percent last year. Even better for the industry, the market hasn?t come close to tapping its potential, as another 6 percent of current non-gamers confessed an interest in playing on their phone over the next year. The reason most often cited for the burgeoning interest is to kill time or alleviate boredom. In fact, the average gaming session is only 11 minutes.
