Saved by the Bell is an American television sitcom that aired on NBC from 1989 to 1993. A reboot of the Disney Channel series Good Morning, Miss Bliss, the show follows a group of friends and their principal. Primarily focusing on lighthearted comedic situations, it occasionally touches on serious social issues, such as drug use, driving under the influence, homelessness, remarriage, death, women's rights, and environmental issues. The series starred Mark-Paul Gosselaar, Dustin Diamond, Lark Voorhies, Dennis Haskins, Tiffani-Amber Thiessen, Elizabeth Berkley, and Mario Lopez.
The show spawned two spin-off series: Saved by the Bell: The College Years (1993–1994), a primetime series that follows several of the characters to college, and Saved by the Bell: The New Class (1993–2000), a Saturday morning series that follows a new group of students at Bayside High School. The series also spawned two TV movies, Saved by the Bell: Hawaiian Style in 1992 and Saved by the Bell: Wedding in Las Vegas in 1994.
In recent years, Saved by the Bell has been classified as educational and informational. The show was named one of the "20 Best School Shows of all Time" by AOL TV.
