After the original cast aged out, they moved on to college (in Saved By The Bell: The College Years) while a new group of kids took over Bayside (Saved By the Bell: The New Class).
The last the cast was seen was in the finale movie Saved By the Bell: Wedding in Las Vegas in 1994.
The influx of new students gives the over-privileged Bayside kids a much-needed and hilarious dose of reality.
Saved By the Bell was one of the most popular Saturday morning series of the ’90s.
