User generated content (UGC), such as that found on YouTube and MySpace, will continue to grow significantly in popularity and generate increasing revenue over the next several years, reports In-Stat. By 2010, the volume of downloads/views on these sites will surpass 65 bln, and revenues tied to UGC video are expected to exceed $850 mln by 2010. The size of downloads/views are estimated to eclipse 1.1 exabytes of data by 2010, with uploads growing to more than 9.1 petabytes. 23% of the dozens of UCG sites studied currently support mobile access, with others making announcements for this support in the near future. YouTube holds the highest market share for video, but MySpace has the most visitors.
