Happy Days is an American television sitcom that first aired this date in 1974 and ran for ten years. The show was originally based on a segment from ABC’s Love, American Style titled “Love and the Television Set,” later retitled “Love and the Happy Days” for syndication. Created by Garry Marshall, the series presents an idealized vision of life in the mid-1950s to mid-1960s in the United States
Set in Milwaukee, Wisconsin, the series revolved around teenager Richie Cunningham (Ron Howard) and his family. Suave ladies man Arthur “Fonzie”/”The Fonz” Fonzarelli (Henry Winkler) became Richie’s best friend and the Cunningham’s upstairs tenant. Fonzie began as a secondary character, but proved to be a favorite with viewers, and more storylines were written to reflect his growing popularity. Each of the eleven seasons of the series roughly tracks the eleven years from 1955 to 1965 in which the show was set.
The show is the basis for the Happy Days musical touring the United States since 2008. The leather jacket worn by Winkler during the series was acquired by the Smithsonian Institution for the permanent collection at the National Museum of American History. (from Wikipedia and cute-calendar.com)
