I Love Lucy is a landmark 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. After the series ended in 1957, however, 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.
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 only by The Andy Griffith Show in 1968 and Seinfeld in 1998). The show is still syndicated in dozens of languages across the world and remains popular with an American audience of 40 million each year. A colorized version of its Christmas episode attracted more than 8 million viewers when CBS aired it in prime time in 2013 – 62 years after the show premiered. A second colorized special, featuring the “L.A. At Last!” and “Lucy and Superman” episodes, aired on May 17, 2015, attracting 6.4 million viewers.
I Love Lucy is often regarded as one of the greatest and most influential sitcoms in history. In 2012, it was voted the ‘Best TV Show of All Time’ in a survey conducted by ABC News and People Magazine. Credit-wikipedia.org
