Not that there's much doubt anymore about Facebook's dominance of the web, but yet another metric comes to prove the point. The site's video section just became the second largest video property in the US, after YouTube, of course, but surpassing Yahoo.

ComScore reports that Facebook has gained enough visitors and enough views to overtake every other video site out there.

YouTube's dominance is not threatened by any means, but it's still a notable feat for the social network which hasn't really focused more than the minimum amount necessary on its video feature.

"Google Sites, driven primarily by video viewing at YouTube.com, ranked as the top online video content property with 146.3 million unique viewers," comScore reports.

"Facebook.com jumped one position to capture the #2 spot with 58.6 million viewers, for a total of 243 million viewing sessions. Yahoo! Sites ranked third with 53.9 million viewers, followed by VEVO with 45.4 million," it adds.

"Google Sites had the highest number of overall viewing sessions with 1.9 billion and average time spent per viewer at 270 minutes, or 4.5 hours," it continues.

In total, 178 million Americans watched a video in August, a significant portion of the internet users in the US. On average, they watched 14.3 hours-worth of video, an ever-increasing number, but still significantly lower than the amount of TV Americans watch every month.

Video advertising seems to be on the rise as well. ComScore says that 3.8 billion video ads were viewed in August in the US. Hulu ran the biggest number of ads, 790 million, to be expected with the long-form content typical on the site. In total, 45 percent of the entire US population saw at least one video ad in August.
