Hulu LogoOne of our favorite sites, Hulu.com, is throwing off the beta-version warm-up and going live March 12. Hulu.com is a joint venture between Universal, NBC and Fox, offering their combined catalog of TV shows and clips free on the web, driven by short commercials, normally in the 10-second range. Hulu.com also delivers content from MGM and Sony, and company representatives have indicated that they’ve reached agreements with Warner Brothers and Lionsgate to include selected content from their libraries.
