Another Hollywood broadband endeavor ... Marshall Herskovitz and Edward Zwick, creators of thirtysomething and My So-Called Life, are bringing new series quarterlife online via MySpace (NYSE: NWS). We’re running a little low when it comes to online video firsts: this one is pitched as the first time a network-quality series will be produced directly for the Internet, something that could be argued. It’s also “the first time an independent project of this distinction has been owned and controlled by its creators, Herskovitz and Zwick.” A better way of putting that: creating a show they own online gives the Emmy-winning duo far more autonomy than they usually get.  (That could be very good or we could see why autonomy’s not all it’s cracked up to be.)

MySpace is the exclusive international distribution partner and MySpaceTV has exclusive premiere rights for the 36 original 8-minute episodes. As part of the deal, the social net is creating a quarterlife video channel and MySpace profile page.

Oddly, at the same time, Herskovotz and Zwick are creating a closed social net for quarterlife; the show is about six creative 20-somethings and the companion social net is meant to “facilitate” the coming of age depicted in the series. Members of quarterlife the social net (not live yet) will have the chance to participate in writing the creating the show through writing and video submissions. That in turn puts MySpace in the business of helping a potential rival.

The trailer goes up with the official announcement Thursday; the show premieres Nov. 11.
