ToonUp At Night 2000

On the night of April 1st, 2000 (the same day that Cartoon Network's Boomerang was launched), ToonUp launched a new late-night block showcasing classic cartoon shorts from the 1930s and 40s. The late night block was first broadcast as an April Fools Joke, but started to air as an actual programming block starting on July 8th, 2000, airing everyday from 10:00pm - 4:00am

ToonUp At Night 2004

On May 1st, 2004, the block was rebranded to match its parent network ToonUp, was well as reformatting as an anime block for teens and adults aged 15-25 due to low ratings as a block for classic cartoon programming, having the block start at 9:00pm instead of its usual 10:00pm start. However, the block was broadcast for the final time on December 20th, 2006. ToonUp said that it would come back after New Year's Eve, but for some reason, the block just never came back, making ToonUp 24 hours a day for the first time since 2000. Until march 8, 2017 ToonUP AT Night return on ToonUP
