ComScore: Yahoo Beats Facebook for Videos Viewed

Maybe web video junkies have the back-to-school blues? According to new numbers released by comScore (s SCOR) today, there was a slight dip in online video viewership last month, with the total number of Internet users watching online video dropping from 178 million in August to 175 million in September. The average amount of video watched remained relatively constant, however: 14.3 hours in August versus 14.4 in September.

Google sites like YouTube (s GOOG) are still heads and shoulders above other competitors, especially when it comes to minutes viewed per user: 260.4 in the case of Google versus runner-up Yahoo (s yhoo) at 31.5. While Yahoo-related video sites only jumped from 53 million viewers in August to 54 million viewers in September, it was enough to supplant Facebook as the number-two viewed video property, especially helped by Facebook dropping from 58 million viewers in August to 52 million. Vevo also took a hit, falling two spots to number six.

In addition, Microsoft (s msft) jumped three spots thanks to its 45 million viewers, perhaps due in part to high-profile projects like the social media reality competition series The Tastemaker.

Break Media (which was ranked above Microsoft in August) does not appear on this chart — ostensibly replaced by Hulu at the number nine spot — however, according to a Break representative via email, “There is an error in all the numbers for Break Media in this month’s comScore reports, and we’re actually in conversations with them right now about it.”

Hulu is still the king of video ads viewed, with viewers watching 27.5 ads per month on average.
