Sesame Street was probably the most influential show that we kids ever had on television. So glad it's still running and still so popular.
I was always allowed to watch Saturday Night Live, as a kid. I was a big fan for a long time, but after Jimmy Fallon left I kind of lost interest. I loved the cast with Mike Myers, Adam Sandler, Dana Carvey, Tim Meadows, Chris Farley, and the like. The Celebrity Jeopardy skits were hilarious too.
80s and 90s TV show honorable mentions: Silver Spoons, St. Elsewhere, Small Wonder
