The average YouTube viewer watched 89.5 videos, compared to 93.4 one month prior. The average video length rose from 4.1 to 4.3 minutes. That might seem like a small increase, but keep in mind that it reflects a vast library of videos. There's a gradual trend towards longer content.
Citizens of the web are adding full-length TV episodes and movies to their usual diet of quick and funny clips, but the clips are still more popular.
Hulu is successful in part because it has a large library of full episodes and films, not just short clips — though it has those too. In January Hulu accounted for 2.8% of videos viewed by U.S. Internet users, but that number rose substantially to 3.2% in February.
Nevertheless, YouTube still dominates the online video landscape. 42.5% of videos viewed in the U.S. in February were hosted on Google's video sites. comScore determined that 174 million people watched online video in the U.S., up one million from January. That's 83.1% of the U.S. online audience.
