Hulu is an OTT subscription service that offers ad-supported on-demand streaming video of TV shows, movies, webisodes and other new media, trailers, clips, and behind-the-scenes footage from NBC, Fox, ABC, CBS, Nickelodeon, and many other network and studios.

It was recently announced that the number of online videos watched by viewers on Hulu, last month, has increased, now making the site second to YouTube, according to the latest online video rankers by comScore. Americans viewed an all-time high of 10.076 billion online video ads during the 31 days of May and Hulu was the highest contributor to the 11-figure metric, with more than 1.666 billion video ads delivered.

Hulu, co-owned by Disney, News Corp. and NBCU, generated more than 887 million videos in May topping Yahoo with 845 million. The average Hulu viewer consumed 253.7 minutes of video, delivering more than 1.6 billion online ads. This is compared to 1.4 billion ads on YouTube.

Although YouTube still attracts the most views to largely user-generated free or promotional material, Hulu is getting the most money from advertisers per online viewer. Hulu generated 25.6 million unique visitors in May compared to 180.5 million viewers for YouTube, but the average Hulu viewer (including subscription VOD subsidiary Hulu Plus) was subjected to 55.5 ad spots compared to 18.6 ad spots per YouTube viewer.

The number of online video ads served from April to May went up from 9,478,975,000 to 10,075,499,000. This is roughly a 6% increase in the number of video ads served month-over-month, a 7% increase in the frequency of online video ads served per video-Great news for online advertisers!
