Judy McGrath is the former chair and CEO of MTV Networks, the Viacom-owned cable behemoth that controls every other cable channel on the dial including MTV, VH1, TV Land, Comedy Central, CMT, and Nickelodeon.

Scranton native McGrath started her career at Mademoiselle and Glamour. With MTV from its days as an upstart, McGrath became president of the network in 1993, where she oversaw the creation of mid-'90s fare like Beavis and Butthead and Singled Out, as well as a well-publicized campaign to put the "M" back in MTV circa 1997, culminating in the creation of TRL.

By 2003, McGrath had moved up to group president of MTV Networks. Things took an abrupt turn in September 2006, though, when McGrath's longtime boss and mentor Tom Freston was fired. Battling speculation that she might leave for years, she finally stepped down in 2011. [Image via Getty]
