I'm a smidge late to this - is it only about kids' shows, or all the shows you watched as a kid?
If just children's television, nothing beat waiting in front of the TV on a Saturday morning, watching the static, waiting for cartoons to come on. We'd watch Bugs Bunny, Scooby-Doo, the Laff-A-Lympics... quite a bit of stuff.
There weren't 24/7 kids shows back then, so we had to watch them when we could. If I got to watch TV in the afternoon on Saturdays I'd watch Doctor Who on (I think) PBS. They'd run all the episodes from a season in one afternoon, and it was silly but fun. Sci/Fi on a $10 (₤10, technically) budget.
Other shows I'd watch, not necessarily kids' shows:
- Magnum P.I.
- Simon & Simon
- Miami Vice
- The A Team
- Airwolf
- Knight Rider
- WKRP (never missed an episode)
- Soap
- Mork & Mindy
- Happy Days
- MASH
