The hit comedy series Happy Days ran from 1974 to 1984. It starred Ron Howard as Richard 'Richie' Cunningham, Henry Winkler as Arthur 'Fonzie' Fonzarelli, Tom Bosley as Howard Cunningham, Marion Ross as Marion Cunningham, Erin Moran as Joanie Cunningham Arcola, Anson Williams as Warren 'Potsie' Weber, Donny Most as Ralph Malph, Pat Morita as Matsuo 'Arnold' Takahashi, Al Molinaro as Alfred 'Al' Delvecchio, and Scott Baio as Charles 'Chachi' Arcola.

The show was set in Milwaukee, Wisconsin in the 1950's and focused on the Cunningham family and their friends. The show lasted for ten years but was almost cancelled after the first season because of low ratings. Luckily Fonzie (Henry Winkler) began to catch on with audiences and ratings increased.

There were several Happy Days spin-offs including Joanie Loves Chachi, Mork & Mindy, and Laverne and Shirley.
