Turner Broadcasting has named Christina Miller as its new president and general manager of Cartoon Network, Adult Swim and Boomerang.

Miller will head up the three networks, along with their digital brand extensions. She replaces Stuart Snyder, Turner’s former president and COO of Animation, Young Adults & Kids Media, who exited the company at the end of March.

In her new role, Miller reports to David Levy, president of Turner Broadcasting. She will lead the business in North America, working with Turner International to create short- and long-term goals, as well as a global strategic plan to more closely align the kids business.

Miller steps into her new role from posts as general manager of NBA Digital and SVP of Turner Sports Strategy/Marketing/Programming. Prior to that, she was SVP of Cartoon Network Enterprises. As SVP, Miller directed Turner’s youth & young adults consumer products and home video business in the US.

Joining Cartoon Network Enterprises in 2005, she was responsible for building the division’s first global multi-property partnership, which brought the entire CN portfolio of toys to market. Before coming on board at Turner, Miller served as SVP of brand licensing for HIT Entertainment.

In her new position, Miller will lead a team of business and creative executives including Rob Sorcher, chief content officer, Cartoon Network, and Mike Lazzo, EVP and creative director of Adult Swim.

Miller’s appointment follows a number of shakeups at the company, including the departures of 14-year Turner vet Paul Condolora and Cartoon Network programming and scheduling SVP Stacy Isenhower.
