J.J. Sedelmaier Productions' relationship with Cartoon Network goes back to before the Turner subsidiary even existed. JJSP helped produce the in-house industrial film used to present research stats to Turner and launch the 24 hour animation channel.

The studio has also produced promo series, interstitials, and series pilot work.

Much of JJSP's animation for CN airs on the Adult Swim block.
