YouTube continues to rank as the No. 1 video Web brand with 5.5 billion total streams in April. Meanwhile, Hulu continued its explosive growth trajectory, increasing 490 percent in total streams year-over-year, from 63.2 million in April 2008 to 373.3 million in April 2009, making it the fastest growing brand among the top 10.

“Historically short form, clip-length video has ruled streaming on the Web—as demonstrated by YouTube’s top spot month after month. Hulu, along with pure-play providers like Veoh and the TV networks, have spent the past two years trying to convince consumers that the Internet can be a good place to watch full length programming as well. April’s strong showings of Hulu, Fox, and ABC suggest that consumers are beginning to listen,” said Jon Gibs, vice president, media & analytics, Nielsen Online.
