After 4-Month Slide, YouTube Regains Viewers & Sessions

After a four-month slide in both unique viewers and video viewing sessions, YouTube rebounded in March to post gains in both of those categories. That’s according to the latest stats from comScore, just released this afternoon.

YouTube remains far and away the dominant video site online, with big leads in both viewers and sessions over second-place AOL and the rest of the sites on comScore’s latest survey.

But these numbers are actually a reversal for YouTube. Since passing the two billion session threshold in October, YouTube has seen those numbers decline each month through February. Its gains in March bring sessions closer to where YouTube was back in November.

YouTube has seen a similar decline in unique viewers over the past four months, according to comScore data. After reaching more than 146 million viewers in October, that number also declined through February.

YouTube’s chart is actually similar to overall video activity. ComScore reported 175 million Internet users watched video in October — a number that dropped to 170 million by February. Likewise, viewing sessions overall dropped from 5.4 billion to 5 billion over the same period.
