Researchers at U.K.-based Screen Digest have issued a new report on the mobile content revolution and which areas of the mobile sector are primed to take advantage of the booming mobile market.

As the oldest form of mobile content, mobile games have certainly evolved quite a bit since 1997 when Snake first became available. Unfortunately for mobile game makers, Screen Digest believes that gaming is in danger of stalling. The market is estimated to be worth about 1.6 billion euros ($2.2 billion), and 50 percent of that revenue is generated by South Korea and Japan. Over the next five years, however, Screen Digest sees mobile games slowing down with only incremental revenue growth. By 2011, it's estimated that the mobile game market will be worth 2 billion euros ($2.7 billion).

According to Screen Digest mobile analyst David MacQueen, the problem is that operators are shifting their focus onto mobile music and TV services, and unless the mobile game business models change, the market slowdown will continue.

As the chart below illustrates, mobile gaming is almost at the point of leveling off while mobile TV services are expected to experience nearly exponential growth. "It is the newest of all mobile content offerings � TV � that looks set to emerge as the strongest performer globally, delivering �4.7bn of revenue from 140 million subscribers by 2011," Screen Digest said. Mobile music, as you can see, is also expected to do quite well over the next five years, reaching 1.47 billion euros by 2011, which would represent an eight fold increase from 2006.
