From Wikipedia:
Coke Time with Eddie Fisher was a musical variety television series starring singer Eddie Fisher which was broadcast by NBC on Wednesday nights in early prime time from 1953 to 1957. The program was aired from 7:30 to 7:45 P.M. Eastern time on Wednesdays and Fridays, and was not seen during the summer months. The program was initially hosted by Don Ameche and Freddy Robbins was the announcer, but in late October 1953 Ameche left the program and Robbins became its host as well. As could have been surmised from the title, the program was sponsored by Coca-Cola. The house band was Axel Stordahl and His Orchestra, and beginning in 1956 the singing group The Echoes appeared as a permanent backup group for Fisher and his frequent guest stars. The program was generally presented live, but was occasionally filmed in advance or shot on location. Coke Time with Eddie Fisher was last aired on February 22, 1957, although the series was by then sponsored by Standard Brands' Planters peanuts, as Coca-Cola previously cancelled their sponsorship during 1956 due to a dispute with bottlers over a proposed larger Coke bottle.
One of the primary purposes served by Coke Time was to round out the balance of the half-hour it shared with John Cameron Swayze's Camel News Caravan (The Huntley-Brinkley Report in 1956-'57), which was then, like all such regularly-scheduled U.S. national newscasts, only 15 minutes in length. After the 1956-57 season, all such brief entertainment programs were discontinued, even though network news broadcasts remained 15 minutes in length until 1963, and afterwards there were no regularly-scheduled prime time entertainment programs of this length remaining on U.S. network television, although there were daytime soap operas of this duration for many more years, and sports programs of roughly this length were often used as fillers to complete the time slots assigned to sports events of uncertain length, particularly boxing matches.
