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 the Columbia Broadcasting System (CBS). When the original series ended, the show continued for three more seasons with 13 one-hour specials, running from 1957 to 1960, known first as The Lucille Ball-Desi Arnaz Show and later in reruns as The Lucy-Desi Comedy Hour.
I Love Lucy was the most watched show in the United States in four of its six seasons, and was the first to end its run at the top of the Nielsen ratings (an accomplishment later matched by The Andy Griffith Show and Seinfeld). I Love Lucy is still syndicated in dozens of languages across the world.
