“Good Times” was a distinctly Seventies show in many ways, but none moreso than its focus on African-American characters. Along with “The Jeffersons” and “Sanford and Son”, it was among the first shows to features a predominantly African-American cast, and after the Civil Rights movement of the 1960s had won new rights for African-Americans, shows like these helped to create a new normal for black and white audiences alike (however much they might have been guilty of tokenism, racism and sexism themselves, they were still improvements on most of the domestic comedies that had preceded them).
The final episode of “Good Times” was entitled “The End of the Rainbow”, and saw each of the major characters given a happy ending in terms of career and domestic arrangements. Since that time, it has been a perennial in syndication, and a steady seller when it was released on DVD
