Animation Domination High-Def

Animation Domination High-Def (also called Animation Domination HD, Fox ADHD, and ADHD) was a late-night programming block broadcast by Fox. Originally premiering on July 21, 2013 as a spin-off of Animation Domination, the block originally focused on new, original adult animation series—similarly in style to Adult Swim. The ninety-minute block and its content were primarily produced by Friends Night, a television animation studio headed by Adult Swim alumni Nick Weidenfeld, Hend Baghdady, and creative director Ben Jones (who also created The Problem Solverz for Cartoon Network)—including its programs, along with interstitials (ADHD Shorts) and other content featured during its programming.

In April 2014, it was reported that Fox planned to discontinue the ADHD block on television that June, citing an inability to reach the correct demographics among viewers; however, ADHD's digital outlets, which feature additional content such as online shorts, continued to operate until March 5, 2016. The block's last airings on Fox consisted only of reruns.
