I never was into Disney Channel with the one exception of Kim Possible, which I loved. Nickelodeon was a mainstay, and holds a special place for me, but nothing will ever top Cartoon Network and its associated Boomerang from back in the day.
Cartoon Network but I’ve spent a good amount of my childhood without cable so it was usually whatever channel had em at the time. Sometimes it was FoxKids cartoon block, other times it was the WB when it came to Sundays and C43 for obscure shit like Freakazoid and Earthworm Jim.
