MTV Networks President & COO Michael Wolf is out as of February after only 15 months in the job. Nicole Browning, president of affiliate sales and marketing who’d been with the company for two decades, is also exiting. My god, Viacom must have a volume deal with Bekins moving company. Tom Freston, Michael Dolan, Gail Berman, Alli Shearmur, now Wolf. (Gawker had the rumor first, then Wall Street Journal got confirmation from Wolf directly.) The ex-consultant who led the media practices at both McKinsey & Co. and Booz Allen Hamilton before joining Viacom in 2005, Wolf told the Journal he “decided to leave because he had accomplished everything he set out to do at the cable network operator. ‘I never viewed this as a long-term thing,’ he said.” Yeah, as if everyone who joins these media companies intends to do the Mike Ovitz-trademarked gone before he got there gig. Wolf insisted to the newspaper that, despite the rumors circulating for months he’d be axed, he wasn’t forced to resign and that his relationship with MTV Networks boss Judy McGrath remained friendly. (What, she stopped banging his head against the wall?) “Michael completed a strong and actionable long-range plan, and brought some of our best and brightest minds in to the company,” McGrath said in a statement. “We know he has a lot to offer the media industry as a whole, and wish him all the best as he moves on to his next adventure.” Viacom said today that MTVN — which includes MTV, Nickelodeon, VH-1 and Comedy Central — will immediately begin searches to replace the execs.
