The growth of US Web video-viewing is pretty phenomenal. We viewed 13.5 billion online videos this past October! Not “million” – “billion”! That’s a 45% increase over October 2007, according to comScore’s latest figures. ComScore measures by the companies that own the sites – so Google topped the list (its YouTube represented 98% of its video-viewing traffic) at 5.4 billion videos viewed (39.7% share). The rest of the top 10 video sites were more clumped together in traffic numbers, the only surprise being Hulu.com’s rapid rise to the No. 6 position. Here are the US’s 10 biggest video-viewing providers, going down from Google: Fox Interactive Media (mostly MySpace) at about 520 million (3.8%); Yahoo Sites 363 million (2.7%); Viacom Digital 305 million (2.3%); Microsoft Sites 286 million (2.1%); Hulu 235 million (1.7%); Turner Network 228 million (1.7%); Disney Online 127 million (0.9%); AOL 123 million (0.9%); and ESPN 105 million (0.8%). BTW, amateur video producers with the most viewers at YouTube are now “earning six-figure incomes from the Web site,” the New York Times reports, because of the ads YouTube puts with them (it has a revenue-share program). See the Times for examples.
