MTV Networks has promoted Judy McGrath to chairman/CEO. She was previously MTV Networks Group president, responsible for MTV, MTV2, VH1, CMT, Comedy Central and the recently announced Logo, set to launch in 2005.

McGrath takes over the chairman/CEO position formerly held by Tom Freston, who was promoted last month to co-president/co-COO of Viacom, MTV's parent company. In her new position, New York-based McGrath reports to Freston.

As chairman/CEO, McGrath oversees MTV, VH1, CMT, MTV2, Nickelodeon, Comedy Central, Spike TV, Logo and MTV Networks International, as well as their spinoff channels, consumer products and digital operations.

Under the new management structure, MTV Networks Group president Herb Scannell and MTV Networks International president Bill Roedy now report to McGrath. Scannell will continue to be responsible for Nickelodeon, Nick at Nite, Spike TV, TV land, Noggin and the N.

In the wake of the changes, MTV Networks president/COO Mark Rosenthal is exiting the company.

At deadline, it was unclear whether McGrath will be replaced at MTV Networks Group. It was also unknown if Rosenthal would be replaced.

MTV Networks and Viacom representatives were unavailable for comment.

In a statement, McGrath says, "I couldn't be more excited and honored to take on this new role. Over the past 17 years, Tom set the tone for the most unique and vibrant culture in the media world. My top priority is to continue to make this the best place for talented people to do their best work. I inherit the strongest management team in the business in Herb Scannell and Bill Roedy, and I can't wait to get started on working with them and their respective teams to take MTV Networks boldly into the future."

McGrath has been with MTV since 1981, when she joined as a copywriter in the on-air promotions department.
