London (England) - Mobile music, video, and online content services, currently still kind of a niche market, will reach a revenue of $150 billion per year by 2011, according to a new report by research firm Informa Telecoms & Media.

Currently, the market for extra mobile services is about $78 billion, but nearly 90% of that is attributed to text messaging, leaving only a little amount of revenue for things like subscription video, mobile music downloading, and information service subscriptions.

By 2011, says Informa, the mobile entertainment market will account for around a quarter of all revenue, or about $38 billion, nearly triple what it was in 2006. Messaging revenues will continue to climb, toppling $93 billion in 2011, according to the report.

The other area it expects revenues to grow is in the market of user-generated content. With the announcement of mobile versions of MySpace and YouTube last year, Informa says pay-per-view content from individual users will grow to $13.2 billion. As of now, there is virtually no revenue from this content, as it is a trend that is just now beginning to be defined.
