Christina Miller to Exit Cartoon Network

Christina Miller, president of Cartoon Network, Adult Swim, Boomerang and TCM, is planning to leave WarnerMedia at the end of the year, after nearly 15 years with the company.

“This is not a decision I came to lightly,” said Miller. “It’s one of the hardest I’ve had to make in my career. Ultimately, it feels like the right time for me to leave and take a little time to think about what comes next, but I do so, feeling immensely proud of the work we’ve done together and so grateful for the experience.”

“Christina has been a respected and impactful leader since she joined the company,” said Ann Sarnoff, chair and CEO of Warner Bros. “We wish her the best of luck in the next chapter of her career, where I know she’ll continue to enjoy great success.”

Michael Ouweleen, executive VP and chief marketing officer for Cartoon Network, Adult Swim and Boomerang, will serve as the interim president. Miller will help with the transition.
