Channel Surfing: Syfy Plans <i>BSG</i> Prequel, McPherson Leaves ABC, NBC Confirms Carell Departure, <i>Parenthood</i>, and More

Welcome to your Wednesday morning television briefing.

The Chicago Tribune's Maureen Ryan is reporting that Syfy is developing an online prequel to Battlestar Galactica entitled Blood & Chrome, which would focus on the life of William Adama during the first Cylon War and will be written by Caprica's Michael Taylor. Project, which would consist of nine to ten episodes of roughly ten minutes each, would focus "about a young man's initiation into war: both the realities of war as fought by soldiers on the ground (and in Battlestars and Vipers), and the somewhat less real version portrayed in the media," according to Taylor. Interestingly, should the online series be a hit, it could serve as the basis for a backdoor pilot or a full-blown series set during the first Cylon War. And, given the fact that it's running online, don't look for any content restrictions. "We're not going to be shying away from R-rated blood and guts and sex," Taylor told Ryan. "Because this is initially meant to air online, we pretty much have no restrictions in that department."

In a stunning move, ABC Entertainment Group President Steve McPherson yesterday resigned from his position, just days before the network's session at the Television Critics Association's Summer Press Tour. He had more than a year left on his contract, which was set to expire in September 2011. "I want to thank the wonderful team of individuals who have worked with me throughout my time here and wish them nothing but the best," said McPherson in an official statement that was released to the press. Deadline's Nellie Andreeva is reporting that ABC has confirmed that Paul Lee, who previously orchestrated huge gains for BBC America and ABC Family, will be moving into McPherson's office and will take over the leadership role at the network, which slipped into third place this year. As for McPherson's next move? "I'll be announcing my future plans shortly which will include a new entrepreneurial venture in the spirits business. While I will continue with my ongoing wine business, I'll also reveal plans for my involvement in a new media company." (Deadline, Variety)

Looks like the show will go on, after all. NBC Primetime Entertainment President Angela Bromstad has said that Steve Carell will be leaving NBC's The Office when his contract expires next year but that the comedy will continue on without him... and will remain in its Thursday night at 9 pm timeslot. "We've been lucky to have had him as long as we've had. These things happen when you have such a major movie star in a show," said Bromstad. "Not to diminish the departure of Steve, because that will impact the show, but we have tremendous faith in the writers and actors to keep it alive." [Editor: my own feelings about what NBC should do have already been discussed in this feature over at The Daily Beast.] (Variety)

I think we're like little containers of peas in that frozen dinner, but we're not quite the Salisbury steak." (Hollywood Reporter)
