Saved by the Bell is an American teen sitcom which originally aired between 1989 and 1993. The series was a retooled version of the 1987 series Good Morning, Miss Bliss, which was later retconned into the history of Saved by the Bell. The series followed the exploits of several students at Bayside High School, along with their principal. The show starred Mark-Paul Gosselaar, Dustin Diamond, Lark Voorhies, and Dennis Haskins, who appeared in Good Morning, Miss Bliss, as well as Tiffani-Amber Thiessen, Elizabeth Berkley, and Mario Lopez who joined the cast for Saved by the Bell. The show brought fame to the cast members and launched most of their careers.
The show was popular enough to spawn two spin-off series: Saved by the Bell: The College Years, which followed several of the characters' college experiences, and Saved by the Bell: The New Class, which followed a new group of students at Bayside High School. The series also spawned two TV movies and a short-lived comic book series.
