George and Junior made their debut on Cartoon Network, often considered one of the worst shorts featured on What A Cartoon.

These shorts were so poorly received that they killed off George and Junior for almost 25 years. The two bears were never used again until 2019 where they were featured in The Tom and Jerry Show episode "Shadow of a Doubt".
