Although YouTube is by far the biggest video site on the Internet, Hulu surpasses its competitor by another measure: the number of video ads it shows viewers each month, reports Michael Learmonth in Advertising Age.

"In fact, no other video site or ad network served as many video ads in the month of June than Hulu, according to new measurement data from comScore," the article says. While Google’s sites, including YouTube and Google’s ad network, served over 200 million ads in June, Hulu presented more than 566 million video ads last month, the story says. Learmonth writes that Hulu was 98% sold out of its inventory in June, and as much as 70% of its advertising revenue is passed on to its content partners and third-party distributors.
