The earliest episodes revolve around Richie and his friends, Potsie Weber and Ralph Malph, with Fonzie as a secondary character. Set in Milwaukee, Wisconsin, during the 1950s, the series revolves around teenager Richie Cunningham and his family: his father, Howard, who owns a hardware store traditional homemaker and mother, Marion younger sister Joanie Cunningham Richie's older brother Chuck (briefly in seasons 1 and 2 only, disappearing from storylines afterward) and high school dropout, leather jacket clad greaser, mechanic and suave ladies' man Fonzie, who would eventually become Richie's best friend and the Cunninghams' over-the-garage tenant. The series also spawned a number of spin-offs, including Laverne & Shirley and Mork & Mindy. Following these changes, Happy Days became the number-one program in television in 1976–1977, Fonzie became one of the most merchandised characters of the 1970s, and Henry Winkler became a major star. The new format emphasized broad comedy and spotlighted the previously minor character of Fonzie, a 'cool' biker and high school dropout. Initially a moderate success, the series' ratings began to fall during its second season, causing Marshall to retool it. The first two seasons of Happy Days focused on the experiences and dilemmas of 'innocent teenager' Richie Cunningham, his family, and his high school friends, attempting to 'honestly depict a wistful look back at adolescence'. Based on the pilot, director George Lucas cast Howard as the lead in his 1973 film American Graffiti, causing ABC to take a renewed interest in the pilot. The series began as an unsold pilot starring Howard, Ross and Anson Williams, which aired in 1972 as a segment titled 'Love and the Television Set' (later retitled 'Love and the Happy Days' for syndication) on ABC's anthology show Love, American Style.

Although it opened to mixed reviews from critics, Happy Days became successful and popular over time. The series presented an idealized vision of life in the 1950s and early 1960s Midwestern United States, and it starred Ron Howard as Richie Cunningham, Henry Winkler as his friend Fonzie, and Tom Bosley and Marion Ross as Richie's parents, Howard and Marion Cunningham.

Created by Garry Marshall, it was one of the most successful series of the 1970s. Happy Days is an American television sitcom that aired first-run on the ABC network from January 15, 1974, to July 19, 1984, with a total of 255 half-hour episodes spanning 11 seasons.
