A recent ComScore survey let us know which sites proved to be the most popular throughout March 2009.

Hulu – 380,102 videos watched

A mere eighteen months old, Hulu is a relative newcomer with its bevy of ad-supported movies and TV shows. Already a joint venture between NBC Universal and the News Corporation, a recent partnership with ABC Enterprises means the site is supported by three of the four major broadcast networks.

Fox Interactive Media – 437,098 videos watched

As the News Corporation’s digital arm, Fox Interactive Media is not only responsible for delivering the popular broadcast network’s shows to the internet; it also oversees sites like IGN and, of course, MySpace. Now, if only Fox would stop cancelling my favorite shows…

YouTube (and other Google properties) – 5,919,530 videos watched

Yeah, that’s right—five million videos. You’re not surprised, are you? The behemoth of video sharing had a bit of a head start; YouTube went live in February 2005 and was purchased by Google, Inc. less than two years later. Add to this the fact that, unlike Hulu or Fox, YouTube is a platform for user-generated (and, in most cases, short) videos and you can see why YouTube holds over 40% of the market share of videos watched in March.

If you are looking for the most popular video on the the internet, you might want to start at the most popular video sites on the web. You can view the most popular videos all time on YouTube and all time on Yahoo.

According to the marketing company the Viral Factory, the footage of Ghyslain Raza – who became known as the Star Wars Kid – has been viewed 900 million times and is the most popular video on web. The company collected view totals from various video web sites and the Star Wars kid was on top as the most popular video.
