The latest online video numbers for the US are in and they paint a very familiar picture, there's hardly any change among the top properties for video from the previous month. In May, 176 million Americans watched at least one video online and, on average, each viewer watched almost 16 hours-worth of videos on the web.

"176 million U.S. Internet users watched online video content in May for an average of 15.9 hours per viewer. The total U.S. Internet audience engaged in more than 5.6 billion viewing sessions during the course of the month," comScore reported.

"Google Sites, driven primarily by video viewing at YouTube.com, ranked as the top online video content property in May with 147.2 million unique viewers, followed by Vevo with 60.4 million viewers and Yahoo! Sites with 55.5 million viewers," the report detailed.

"Facebook.com came in fourth with 48.2 million viewers, while Viacom Digital ranked fifth with 46.5 million viewers," it added.

No big surprises in the top five websites at all. Google continues to dominate, as it always has, completely obliterating all competition in all metrics. This is the first time users watched more than five hours of video on the site.

In total, 147 million people watched a YouTube video, while only 60 million watched a video on Vevo, the runner-up.

VEVO had a strong showing, it also had the second most views and almost the second most minutes per viewer, only Hulu came in front. Considering that Vevo is powered by YouTube and that they share videos, it should give you an idea of just how big YouTube is.

Yahoo is the first real competition to YouTube, but it is very far behind with just 55 million viewers and 272 million views. Facebook is following closely with 48 million viewers and 176 million views.

Still, considering just how big Facebook Photos is, completely dwarfing anything else on the web, it does seem that if the social network can find a way of doing for video what it did to photos, it's going to give YouTube a run for its money and it's probably the only site that could.
