ComScore Video Rankings: YouTube Usage Spiked 72 Percent Over 2010

As it seeks to launch nearly 100 new channels featuring professionally produced video, YouTube has a key advantage over original video competitors like Hulu and Yahoo: millions more viewers can see its promos.

According to comScore’s latest monthly report on online video usage, Google – driven primarily by the performance of YouTube – drew 157.2 million unique viewers to its video offerings in December. That marked a 9 percent rise from December 2010 and represented 86 percent of the total internet audience for the month, according to comScore. And with YouTube focusing on longer form, professionally produced video in its dedicated “TV” channels—not to mention other offerings like full-length movies—usage per unique viewer shot up 72 percent year-to-year to an average of 471.9 minutes per viewer.
