About the data: All data cited here comes from Nielsen's September US Online Video Usage report. Effective with June 2009 data reporting, Nielsen has made several enhancements to the VideoCensus service. For some sites, trending of previously reported data with current results may show percentage differences attributable to these product enhancements and should only be compared directionally. Online video viewing is tracked according to video player, which can be used on site or embedded elsewhere on the Web. For example, if a “Saturday Night Live” clip from NBC.com is embedded on a personal blog, that video would be attributed to NBC because of the NBC video player.
