Two types of online-video purveyors are competing for advertisers.
Hulu doesn”t disclose its finances, but online advertising experts estimate that its advertising rates are several times higher than YouTube”s.

‘Generating revenue from user-generated content is very, very difficult, and that”s probably being generous,’ said Josh Martin, a senior analyst at the Yankee Group, a technology-research firm based in Boston. ‘The reason Hulu”s been successful is that it”s providing the content that people want.’

That”s left YouTube to play catchup. Since November, the company has added TV shows, movies and other videos from the likes of Sony Pictures, CBS, MGM and ABC. This month, the site added a new section called ‘Shows’ to promote its collection of Hollywood-produced videos.

YouTube now has more than 500 Hollywood movies on its site, including Super Size Me and the recent remake of The Mod Squad.more
