The longest-running Saved by the Bell TV show might actually be the least known. It's not streaming in full, it's hard to find on physical media, and it might not even be considered SBTBcanon. But Saved by the Bell: The New Class kept the Bayside story going on Saturday- morning NBC long after Zack, AC, Jessie, and the rest of the original Saved by the Bell gang graduated. Here's the lowdown on the little-remembered spinoff.
Dennis Haskins is credited for all 143 episodes of The New Class, reprising his part as Mr. Belding, principal of Bayside. Dustin Diamond joined the cast in Season 2 -- in the aptly titled "The Return of Screech" -- as Screech returns to the school as Mr. Belding's assistant.
Image Entertainment released all seven seasons of Saved by the Bell: The New Class on DVD in 2005. However, the DVD sets seem to be out of print, and third-party listings on Amazon go up to $250 per set.
