37 billion. That's the number of online videos watched by Americans last month. In the United States, ComScore found that 181 million users watched 37 billion online videos last month. That means that 84.5% of United States Internet users watched at least one video last month. Incredibly, the average person watched 21.8 hours of video during the month.

Of course, Google grabbed the large majority of the viewers with 157.7. Second place went to Yahoo with only 53.6 million. Beyond that was Vevo, Facebook, and Microsoft with 49.5, 44.3, and 42.8 million viewers respectively. Hulu was even further down the list grabbing only 28.2 million views yet they came in just behind Google in terms of total time spent by the average user at 3.8 hours.

Video ads were also shown quite a few times in order to pay for the videos. 9.5 billion video ads were shown to users last month with Hulu showing the majority of those ads. This fact isn't surprising as viewers have to sit through the ads in the middle of their favorite TV shows. Video ads also accounted for 20.5% of all videos watched last month.
