#4: Garry Marshall and His Writing Team Develop a Sitcom Around Blue-Collar Women in 1975
In 1975, Garry Marshall and his writing team began shaping two new characters who could appear in the world of Happy Days. The idea centered on a pair of working-class women who lived in the same Milwaukee neighborhood as Richie Cunningham and his friends.

Unlike many television heroines of the time, these characters were not glamorous professionals or socialites. They were ordinary young women navigating factory jobs, friendships, and everyday problems. The concept created a contrast with the more traditional characters on Happy Days and gave the show a fresh comedic angle.
