In the Wild West that is online video, Hulu.com has proven to be a trailblazing answer to how professional content can thrive on the Web.

It's this year's pick for Web site of the year.

"This is period of great experimentation in regard to media, in regard to online video," said Hulu chief executive officer Jason Kilar in a recent interview. "You've seen a lot, you're probably going to see even more in terms of various business models, various interface designs. I personally love to operate in moments of time like that."

YouTube, the biggest online video Web site, has been missing much of the action as studios move full-length TV shows and movies to the Web. But this may be changing: YouTube announced Monday that movie studio Metro-Goldwyn-Mayer (MGM) will show some of its archive on the popular video site.

The fare will be free for viewers, accompanied by ads. Initial titles from MGM include episodes of the American Gladiators TV series, full-length films such as Bulletproof Monk and The Magnificent Seven, and clips from movies like Legally Blonde.
