NBC and News Corp.'s joint online-video venture has gone unnamed so long that it's reaching the point of total absurdity. It now has a CEO, even — former Amazon executive Jason Kilar — but still no name. The clock is counting down, since "NewCo," as NBC and News Corp. employees still style it, appears set to launch in a month. George Kliavkoff, NBC's chief digital officer resorts to calling it "the new site" in an interview with ClickZ . NBBC, NBC's digital-video distribution arm, is getting folded into NewCo and is winding down its current ad campaigns over the next 30 days, which suggests an imminent launch. Just one question: To whom are advertisers going to make out their checks?
