The joint venture of General Electric's NBC Universal and Rupert Murdoch's News Corp, which earlier had trouble persuading other big content producers such as Viacom Inc and Walt Disney Co to join, now adds shows from Sony Pictures Television and Metro-Goldwyn-Mayer Studios Inc., Hulu executives said.

Hulu will offer about 90 TV shows from the four companies and smaller partners ranging from current prime-time hits such as "Heroes" and "The Simpsons" to vintage shows "Miami Vice" and "The A-Team."

It will also make about 10 feature films available including "The Breakfast Club" and "The Blues Brothers."

Shortly after the test begins, these shows will also be made available on a handful of the biggest online distributors Time Warner Inc's AOL, Comcast Corp, Microsoft's MSN and Yahoo.

One distinguishing features created by a team that consists almost entirely of executives from the Internet and technology industries, addresses an issue that is unique to its service -- the ability to find a spot within a show that a viewer wants to share.

Viewers can adjust a slider at the bottom of the video window to clip the exact spot within a show -- a particularly funny skit on "Saturday Night Live" for instance -- to send or embed on another Web page.
