It looks like Pinterest isn’t the only site Yahoo needs to watch out for. According to comScore, Facebook surpassed the company in July to become the second largest video site in the U.S.

During the month of July, more than 184 million U.S. Internet users watched 36.9 billion online videos in July. Additionally, video ad views totaled 9.6 billion.

comScore’s monthly online video data revealed that Facebook had more than 53 million unique viewers in July, putting it directly behind Google and YouTube — which dominated with 157 million unique viewers. Yahoo, on the other hand, saw just under 48.7 million. Rounding out the top five are VEVO and Microsoft, with 44.8 million and 42.7 million, respectively.

Google also took the top spot for engagement with 525.0 minutes per viewer. But while Facebook trumped Yahoo in viewers, the same can’t be said this category. Yahoo’s engagement ranked at 70.4 minutes per viewer, whereas Facebook sits at 21.7.

When it comes to advertising, Google unsurprisingly ranked first with 1.5 billion ads viewed, followed by Hulu with 1.2 billion, and Adap.tv with 1.1 billion — which delivered the highest duration of video ads at 627 million minutes.

It’s likely these numbers will fluctuate over the next few months — Facebook actually fell behind Yahoo and VEVO in May. We don’t recommend that you restrategize based off these figures alone, but it’s something to keep in mind while sharing your video content.
