Eileen O’Neill
President and GM
TLC

Eileen O'Neill leads all key business functions at TLC, including development, programming, production, digital media, marketing, research and communications. She works in partnership with ad sales and affiliate sales to generate revenue and increase the value of the TLC brand.
Before assuming responsibility for TLC in July 2008, O'Neill served as president and general manager of Planet Green, the first and only 24-hour eco-lifestyle television network. She is credited with launching the network from the ground up in less than 12 months, and with more than 250 hours of all-original programming. She drew an authoritative and diverse group of celebrities and personalities including Adrian Grenier, Tom Bergeron, Emeril Lagasse, Maria Menounos, Tom Brokaw and Bob Woodruff to share their passion for the planet through a host of entertaining series and specials.
O'Neill also previously served as executive vice president and general manager of Discovery Health Channel. In 2007, she simultaneously ran Discovery Health and TLC on an interim basis during a period of management transition at TLC.
Under O'Neill, Discovery Health earned record ratings in all day-parts, including the strongest delivery ever during August 2005. Standout shows developed under her leadership include MYSTERY DIAGNOSIS, DR. G MEDICAL EXAMINER and JON & KATE PLUS 8, now the top-rated series on TLC.
Prior to joining Discovery Health, O'Neill was director of scheduling for Travel Channel, and earlier she served as director of business affairs, responsible for all contract negotiations concerning co-productions, commissioned programming and original work for Discovery Channel, TLC and Animal Planet.
O'Neill describes herself as "homegrown talent," having started at Discovery Communications as an unpaid intern while earning a graduate degree in popular culture from Bowling Green State University in Ohio. Having successfully developed a programming library that earned the respect of her professional mentors, she was hired by DCI's networks operation department immediately upon graduation.
