More US consumers watched online videos in March, according to figures released on Tuesday by Nielsen, but they watched fewer videos than in the year-prior period.

Unique viewers grew 1.3% year-over-year to 131.7 million but the number of views dropped 4.2% to 9.3 billion – at least one billion streams fewer than each of the previous three months. Time per viewer dropped 3.8% but has been very steady since December.

YouTube maintained its title as dominant online video brand by amassing 96 million unique viewers. But that was an 11.7% drop from February. Many other brands, from Fox Interactive Media to MSN/Windows Live/Bing and Hulu, were in negative territory as well.

Second-place Yahoo! grew over 19% from February to 30.5 million viewers. Fourth-place Google jumped 123% to 15.2 million viewers. Eighth-place Disney grew 40% to 9 million viewers.

In terms of time spent viewing, however, Netflix ranked No. 1 with 429 minutes per viewer while Hulu was No. 2 with 272 minutes per viewer. Netflix wasn’t even in the top ten last month. Its 963% growth from February was likely to result of a change in Nielsen’s VideoCensus survey.

Justin.tv ranked fifth in time per viewer with 162 minutes while Veoh, which earlier this month was saved from bankruptcy by a purchase from Qlipso, ranked eighth at 137 minutes.
