TheWB.com detailed, Buffy, Mars included

Warner Brothers is launching online arm with full episodes of shows such as Gilmore Girls, Everwood.

The WB is back, baby ! The defunct television network is getting revived online in the form of TheWB.com, where it will stream old shows from its library as well as original content from some big-name television producers, Warner Bros. Television Group announced.

First hinted at over a month ago, the new online enterprise will play home to some of television’s most beloved teen-aimed shows, including Buffy the Vampire Slayer, Gilmore Girls, and Veronica Mars. The episodes will be free and ad-supported, and will mainly target women in the prized 16-to-34-year-old group.

Other shows mentioned by Warner Bros. to stream online include Friends, Smallville, The O.C., Everwood, Roswell, The Wayans Bros., All of Us, and One Tree Hill.

In addition to streaming these shows online, Warner Bros. is partnering with cable operator Comcast to stream the aforementioned shows on Fancast.com and through its on-demand service.

Original content is also headed to the Web site, and it isn’t film school grads uploading their student projects. Producers McG and Josh Schwartz (Chuck, Gossip Girl, The O.C.) are putting together a handful of projects for the site, as are half a dozen other television veterans.

TheWB.com will also—just like every other Web site out there—incorporate a social networking element, allowing fans to chat each other up about how awesome Tom Welling looks or whatever else is on their minds.

A beta version of the site is scheduled to open in early May. The company did not reveal how it will distribute beta invites.
