From Wikipedia:
The Lucy–Desi Comedy Hour is a collection of thirteen black-and-white one-hour specials airing occasionally from 1957 to 1960 (as opposed to a thirty-minute regular series). The first five were shown as specials during the 1957-58 television season. The remaining eight were originally shown as part of Westinghouse Desilu Playhouse. Its original network title was The Ford Lucille Ball-Desi Arnaz Show for the first season, and The Westinghouse Desilu Playhouse Presents The Lucille Ball-Desi Arnaz Show for the following seasons. The successor to the classic comedy, I Love Lucy, the programs featured the same cast members: Lucille Ball, Desi Arnaz, Vivian Vance, William Frawley and Little Ricky (billed as Richard Keith in his post-Lucy-Desi acting assignments). The production schedule avoided the grind of a regular weekly series.
Desilu produced the show, which was mostly filmed at their Los Angeles studios with occasional on-location shoots at Lake Arrowhead, Las Vegas and Sun Valley, Idaho. CBS reran these thirteen specials under the "Lucy-Desi" title as five prime time summer replacements, from 1962 to 1965, with a final run in 1967. 1966–67 was the first TV season in which all first-run prime time network shows were in color. These "Lucy-Desi" repeats were the only black and white series aired that year, after which it, and I Love Lucy, went into syndication.
