According to a new report from Juniper Research, end-user generated revenues from social networking, dating and personal content delivery services will increase from this year's $572 million to $5.7 billion in 2012. Social networking is forecast to account for half of such revenues. Currenly, mobile dating and chatrooms account for 57% of revenues, a number that will fall to 21% in five years. In the medium term, the highest levels of growth may come from developing markets with limited broadband access, where the mobile phone is the main means of access to the Web.
