Key Points
1
Toonami, launched on Cartoon Network in 1997, helped expose Western audiences to anime long before mainstream streaming; Register later supported anime projects including new seasons of FLCL.
2
Adult Swim, launched in 2001 under Register, brought adult animation to a mainstream audience and fostered creator-driven hits such as Rick & Morty, Space Ghost Coast to Coast, and Primal, while reruns of Family Guy and Futurama helped revive those shows.

Register helped broaden Warner Bros. Animation's distribution by developing shows for external streaming platforms, moving beyond a linear-to-HBO Max pipeline and expanding the studio’s deal flows with other streamers.

During his tenure, WB Animation produced a diverse slate including Looney Tunes Cartoons, the Animaniacs revival, Harley Quinn, Young Justice, Teen Titans Go!, Genndy Tartakovsky's Primal and Unikitty!, plus executive producing Teen Titans Go! to the Movies and the Tom and Jerry live-action/animated film.

Career milestones include starting at Cartoon Network in 1994, launching the network’s first website in 1998, joining Warner Bros. Animation in 2007, becoming executive VP of creative affairs in 2008, adding Cartoon Network Studios oversight in 2020, and an 18-year tenure leading WB Animation, with a staff transition plan underway as a successor search begins and Matt Matzkin remains to lead business operations.
Sam Register, the longtime president of Warner Bros. Animation and Cartoon Network Studios, is departing the company next week after 18 years in the role. Warner Bros. TV chair Channing Dungey confirmed the mutually-agreed exit, marking the end of an era for one of animation's most influential executives. Register's departure leaves a significant void in WB's animation strategy as the company searches for a successor.
Building Toonami and Adult Swim into Cultural Forces
Register's career at Cartoon Network began in 1994, when the network was still finding its voice. He helped launch Toonami in 1997, a programming block that introduced Western audiences to anime years before streaming made it mainstream. Animation Magazine notes his role in expanding anime projects, including supporting new seasons of cult hit FLCL. His early website work in 1998 helped establish Cartoon Network's digital presence during the internet's infancy.
In 2001, Register championed Adult Swim, a late-night block that became the launchpad for creator-driven hits like Rick & Morty, Space Ghost Coast to Coast, and Primal. The channel also revived struggling shows by running reruns of Family Guy and Futurama, proving that adult animation had mainstream appeal. Adult Swim became Warner's testing ground for bold, experimental storytelling that traditional networks would never green-light.
Expanding Animation Beyond HBO Max to All Streamers
When Register joined Warner Bros. Animation as a full executive in 2007, the studio was primarily focused on internal distribution. C21 Media reports that Register broadened the studio's reach by cutting deals with external streaming platforms, moving beyond a linear-to-HBO Max pipeline. This shift allowed WB Animation to compete globally and maximize revenue across Netflix, Apple, Amazon, and other services. The strategy proved crucial as traditional TV advertising collapsed.
Register's tenure produced a diverse slate across multiple platforms: Looney Tunes Cartoons, the Animaniacs revival, Harley Quinn, Young Justice, and Teen Titans Go!. He also executive-produced theatrical films including Teen Titans Go! to the Movies and the Tom and Jerry live-action/animated hybrid. By 2020, when he added Cartoon Network Studios oversight, Register controlled one of the most prolific animation factories in entertainment.
A Surprise Departure Leaves WB's Animation Future Uncertain
AWN reports that Register's exit came as a surprise to colleagues, despite the "mutually-agreed" framing. His 18-year run at WB Animation—added to a prior decade at Cartoon Network—gave him unmatched influence over what audiences watched. Newsy Today confirms that a replacement search is now underway, while business operations remain stable under Matt Matzkin's leadership. The company has not yet named a successor or outlined its animation priorities under new leadership.
Register leaves behind a legacy that reshaped Western animation. His block-programming innovations, creator relationships, and platform-agnostic distribution model became industry standard. The question now is whether his successor can maintain WB Animation's momentum, or if the departure signals a strategic shift at Warner Bros. Discovery. The company's next move will define animation for the next generation.
