[4][5] In seven years there, Weidenfeld developed, among others, Robot Chicken, the Peabody Award-winning animated series The Boondocks, Delocated, and Childrens Hospital,[1][5][6] in addition to providing the voice of Peanut Cop in 12 oz.

[10] In February 2012, then Fox President, Kevin Reilly tapped Weidenfeld to lead the network's foray into late-night Saturday animation.

[11] Dubbed Animation Domination High-Def (ADHD), the 90-minute programming block would be filled with 15-minute shows broken up by shorter bits.

[4] Fox took the underperforming experiment off the air in June 2014 because it failed to reach the target audience and upset too many of the network's older viewers.

[12] Two ADHD series were moved to primetime, while others continued on digital platforms,[13] before they shifted to a new late-night animation block on sister channel FX in 2015.

[14] Weidenfeld was hired in April 2016 as the president of programming for Viceland, a youth-oriented television channel that is a joint venture between A&E Networks and Vice Media.
