MTV's Judy McGrath resigns

Routinely included on lists of the most powerful women in the entertainment industry, McGrath was at MTV almost from the start, beginning as a copywriter in 1981. She's been chairman of MTV Networks since 2004 (the group includes MTV, MTV2, VH1, Logo, Nickelodeon, Nick at Nite, Comedy Central, TV Land and Spike). Over the years, there has been speculation that she would leave for any number of posts, including as head of Oprah Winfrey's OWN. "We respect her decision and understand her desire to leave at the very top of the game with a legacy of success that stretches from the earliest days of cable television to current season highlights," said Viacom CEO Philippe Dauman. There will be no replacement for McGrath - Dauman is said to want direct oversight of the company's cable divisions. (Deadline, LAT)
