I Love Lucy is an American television sitcom starring Lucille Ball, Desi Arnaz, Vivian Vance, and William Frawley. The black-and-white series originally ran from October 15, 1951, to May 6, 1957, on CBS. All 180 episodes aired on Mondays.
In total 180 episodes of I Love Lucy were produced, plus a pilot episode. The pilot, which was not made for broadcast and did not air as part of the show's original run, is generally not counted as one of the episodes and therefore listed separately for reference. It is, however, available on DVD and Blu-ray releases of the first season. Following I Love Lucy, a further 13 one hour-long episodes were produced under the title of The Lucille Ball-Desi Arnaz Show (later and more commonly known in syndication as The Lucy–Desi Comedy Hour) with the same cast and later packaged as seasons 7, 8 & 9 under the I Love Lucy series.
