passage: I Love Lucy
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.

Another well-known lineup was the "Lucy: Queen of Comedy" block which ran on Saturday nights from June 4, 1994 to May 3, 1996, which consisted of "I Love Lucy", "The Lucy Show" and "The Lucy-Desi Comedy Hour", which were all airing on the network at that time (a similar block called "A Whole Lotta Lucy" aired on Saturday nights from 1996 to 2001, featuring only "I Love Lucy", and "The Lucy-Desi Comedy Hour"). In the mid-1990s, another Saturday night programming block titled "Very, Very Nick at Nite" centered around a different theme each week, such as "Very Very Mary" with four classic "Mary Tyler Moore Show" episodes. In summer of 2008, Nick at Nite aired a marathon called "Battle of the Sexes", which featured episodes of their regular programs that involved conflict between men and women.
