After more than half a decade as Turner’s Animation, Young Adults & Kids Media president and COO, Stuart Snyder is set to depart from the company at the end of this month.

Some of the accomplishments achieved under Snyder’s watch include Adult Swim achieving its best ratings ever in 2013 and Cartoon Network launching its pro-social Stop Bullying: Speak Up campaign.

Snyder held earlier roles within Turner, including a stint as SVP and GM of GameTap, an early experiment in subscriber-based content delivered via broadband, and he led Turner’s home entertainment division during the ’90s boom years of home video.

Snyder’s departure, which is amid continued management changes at Turner and parent company TBS, comes as Cartoon Network heads into its upfront marketplace, and as the company gears up to launch a new portfolio of original web content for CartoonNetwork.com and introduce ads to its 24-hour kidsnet Boomerang in the US.
