Stu Snyder, president and chief operating officer of Time Warner's Turner Animation unit, is exiting.
Snyder, who has overseen Turner's animation efforts, including the Cartoon Network, for six years, told his staff that he is resigning at the end of the month.
"It is with mixed emotions that I share with you the news that I will be leaving the company at the end of the month," Snyder said in an email. "I have had the privilege of working and partnering with some of the most creative, talented and fun people in the business, who I will miss working with every day."
Snyder's departure comes in the wake of a new management regime taking the reins at Turner. In January, John Martin was promoted from chief financial officer of Time Warner to chief executive of Turner. As part of the restructuring, David Levy, Turner's head of sales and distribution, was named president.
Tensions between Snyder and Levy led to the former's decision to resign, a person familiar with the matter said who requested anonymity because of the sensitivity of the situation.
In his own email to staff, Levy praised Snyder's tenure but added that "this is an opportunity for fresh thinking."
No replacement for Snyder has been named.
Cartoon Network is best known for "Adult Swim," its popular prime-time block of animated shows aimed at the 18-34 demographic.
