I Love Lucy is a popular 1950s American television sitcom that originally ran on CBS from October 15, 1951, to May 6, 1957, with a total of 180 half-hour episodes spanning 6 seasons (including the 'lost' original pilot and Christmas episode). The show starred Lucille Ball, her real-life husband Desi Arnaz, Vivian Vance, and William Frawley. It followed the life of Lucy Ricardo (Ball), a middle class housewife in New York City, who either concocted plans with her best friends (Vance & Frawley) to appear alongside her bandleader husband Ricky Ricardo (Arnaz) in his nightclub, or tried numerous schemes to mingle with, or be a part of show business. After the series ended in 1957, a modified version continued for three more seasons with 13 one-hour specials; it ran from 1957 to 1960. It was first known as The Lucille Ball-Desi Arnaz Show and later in reruns as The Lucy–Desi Comedy Hour. Following the end of that, Ball divorced Arnaz and appeared in three other sitcoms into 1986.
