While Degrassi has been popular around the world, it's not actually a show on Nickelodeon. The show has aired on various networks over the years, including:
* CTV (Canada): The original Degrassi series and its spinoffs (Degrassi Junior High, Degrassi High, Degrassi: The Next Generation, Degrassi: Next Class) aired on CTV.
* The N (US): The N, a former Nickelodeon-owned channel, aired Degrassi: The Next Generation.
* TeenNick (US): TeenNick, another Nickelodeon-owned channel, aired Degrassi: The Next Generation and Degrassi: Next Class.
So, while Degrassi characters don't specifically appear on Nickelodeon's main programming, you can find them on TeenNick, a channel focused on teenagers.
