There may be a limit to how many videos consumers want to view on the Internet, but according to the latest research from comScore, we haven’t hit the peak just yet.

According to comScore, more than 180 million U.S. Internet users watched online videos during the month of March, which was a 3.5 percent increase over February.

Google’s YouTube is still the king of the mountain when it comes to serving up online videos. YouTube’s number of videos viewed increased from 11.95 billion in February to 13.05 billion in March. YouTube delivered video to more than 135 million viewers during the month, reaching three out of every four online video viewers at an average of 96 videos per viewer.

Hulu ranked second with 1.1 billion videos, or 3.4 percent of all online videos viewed. The average Hulu viewer watched 27 videos, totaling 2.6 hours of video per viewer.

While Hulu’s content is free due to an ad-supported revenue model, it’s reportedly looking at a subscription service.

Microsoft Sites ranked third with 655 million (2.1 percent), followed by Yahoo! Sites with 478 million (1.5 percent) and CBS Interactive with 457 million (1.5 percent).
