3. Saved by the Bell (1989-1993)
Ever head of Good Morning, Miss Bliss? That’s where Saved by the Bell began. It ran from 1987 to 1989, featuring Hayley Mills as Miss Carrie Bliss, a teacher at Indianapolis’ Kennedy Junior High. The show featured a group of kids, including a few characters names that may sound familiar — Zack Morris, Screech Powers, Lisa Turtle, and Mr. Belding. The show was originally scheduled to run on NBC, however, it ended up airing on the Disney Channel for a season after its pilot didn’t do well on NBC. A 1989 reboot of the show moved the focus from the teachers to the students, and Mills and some of the other actors were given the boot. But Zack, Screech, Lisa and Mr. B remained, and were then joined by Slater, Jessie and Kelly.
