After a hot streak all summer long, online video stats are a bit more of a mixed bag for September, according to Nielsen. Though Nielsen’s measure of the number of unique U.S. viewers was up slightly to 139 million, the number of total streams dropped 3 percent to 11.02 billion.
While streams per viewer and time spent per viewer were both up year-over-year, they were down from August.
Facebook, which has been in comScore’s top 10 rankings in terms of unique viewers, cracked Nielsen’s list with 110 million streams to 23.1 million unique viewers. While Facebook rose, YouTube hit a rough patch. The video giant dropped both in total streams in Sept. to 6.8 billion (vs. 7.18 billion in Aug.) and 106 million unique viewers (vs. 107 million in Aug.). The new fall season buoyed Hulu, which saw nice gains on both fronts. During Sept., Hulu served up 437 million streams (vs. 392 in Aug.) to 13.5 million viewers (vs. 9.8 million in Aug.).
Nielsen and comScore often disagree on video viewing trends; we’ll have to see if these shake-ups are echoed by comScore when its numbers come out later this month.
