Concentration was originally slated to debut on NBC on July 28, 1958, but its debut ended up being delayed until August 25, 1958.
Concentration was first hosted by
Hugh Downs, who was also the announcer for
Tonight Starring Jack Paar and working as one of the NBC Radio Monitor staff.
Concentration was broadcast at the time that
Truth or Consequences had been aired; NBC moved
Truth or Consequences to its afternoon schedule.
Concentration remains the longest-running game show on NBC and held the record for longest continuous daytime run on network television until it was eclipsed in March 1987 by the CBS daytime version of
The Price Is Right (beginning September 4, 1972).
Concentration is currently the sixth longest-running daytime/syndicated game show behind
The Price Is Right and the syndicated versions of
Wheel of Fortune (1983–present),
Jeopardy! (1984–present),
Family Feud (1999–present), and
Who Wants to Be a Millionaire (2002-2019).
Concentration was an NBC in-house production, apart from the earliest episodes. As a result of the
1950s quiz scandals, the network purchased the rights to
Concentration and three other games (
Twenty-One,
Dough Re Mi and
Tic-Tac-Dough) from producers Barry and Enright. NBC/Universal still holds exclusive rights to both the format and extant episodes of
Concentration; however, due to
Financial Interest and Syndication Rules, this version is owned by
CBS Media Ventures. The show was produced and broadcast live at 11:30 am Eastern on weekdays in black-and-white, and quickly became the most-watched daytime series in NBC's lineup. The announcer was
Art James, who sometimes served as a substitute host and later became a game show host in his own right. The series was produced in NBC's Studio 3A which now houses
NBC News and
MSNBC. In 1958 and 1961, the show had two brief runs in prime time: one hosted by Jack Barry, the other by Downs. The series then moved to 11:00 am and slowly introduced color broadcasts. For a picture puzzle game whose rebuses were designed and painted in monochrome, this required some design changes: The colors of the numbered cards might otherwise interfere with the colors used on the rebus, a critical issue for contestants playing in the studio and for viewers who played along at home. During this period, the series was produced in NBC's Studio 6A. Hugh Downs, by this time also an anchor correspondent on NBC's
Today Show, remained host, and the announcer became Jim Lucas, who also worked on NBC's local New York radio station,
WNBC (AM). In September 1965, the show moved to 10:30 am where it would spend the remainder of its run on NBC. The show fully converted to color on November 7, 1966. In January 1969, Downs stepped down to devote his entire attention to
Today. Bob Clayton, who had succeeded Jim Lucas as announcer, took over the hosting duties; he was introduced as the new host at the program's 1968 Christmas episode, dressed as Santa Claus. NBC staffer
Wayne Howell moved to the announcer's booth during Clayton's tenure as host. However, in March, advertiser pressure led NBC to set Clayton aside in favor of
Ed McMahon; after viewer complaints and declining ratings, Clayton returned in September and remained host until the series ended on March 23, 1973. (On the Monday following
Concentration's cancellation, Clayton became the announcer for
The $10,000 Pyramid on
CBS.)
Cancellation For most of its run,
Concentration faced sitcom reruns on
CBS and local programming on
ABC affiliates, easily dominating them in the ratings. However, in September 1972, CBS launched
The New Price Is Right at 10:30/9:30 and drained off more than half of the
Concentration audience. Rather than move the game, NBC concluded that it had reached the end of its life and cancelled it in March 1973. While the first puzzle on the debut was "It Happened One Night", the last puzzle on the finale was "You've Been More Than Kind". After Clayton said a final goodbye, the credits rolled over a rendition of "
Auld Lang Syne".
Baffle, a
Merrill Heatter-Bob Quigley production hosted by
Dick Enberg, replaced it at that time slot and ran until March 29, 1974. ==Syndication (1973–1978)==
