Google — thanks mainly to YouTube — ranked on top in comScore’s January 2012 list of online video content properties.
In January, 181 million U.S. Internet users watched nearly 40 billion online videos, according to comScore. Of those, nearly 152 million watched on Google sites — primarily YouTube.
The falloff in users from first to second place was sharp: Second-ranked online music video site Vevo had 51.5 million viewers, and third-place Yahoo sites had 49.2 million. Microsoft sites ranked sixth with 41.5 million viewers.

In other comScore findings, the research firm showed Microsoft sites — including MSN, MSNBC, Bing, Microsoft.com and others — ranked second among the top 50 U.S. web properties in January.
The Microsoft sites garnered 179.2 million unique visitors. The list leader was, again, Google, whose sites garnered 187.4 million visitors.
The rankings among the top five remain unchanged from December. Following Google and Microsoft, the other three on top were Yahoo sites, Facebook and Amazon sites.
