From Wikipedia:
Let's Make a Deal is a television game show which originated in the United States and has since been produced in many countries throughout the world. The show is based around deals offered to members of the audience by the host. The contestants usually have to weigh the possibility of an offer being for a valuable prize, or an undesirable item, referred to as a "zonk". Let's Make a Deal is also known for the various unusual and crazy costumes worn by audience members, who dressed up that way in order to increase their chances of being selected as a contestant. The show was hosted for many years by Monty Hall, who co-produced the show with Stefan Hatos.
The original and most widely-known version of the show aired from 1963 to 1976 on both NBC and ABC. A weekly nighttime syndicated version of the show aired from 1971 to 1977. Two daily syndicated versions aired in the 1980s. A show based in Canada aired from 1980 to 1981, while The All New Let's Make a Deal aired from 1984 to 1986. NBC aired a daytime series in 1990-1991 and three episodes of a weekly prime time version in 2003.
The weekly nighttime syndicated version, seen from 1971-1977, was distributed by ABC Films and its successor, Worldvision Enterprises. The 1980 daily syndicated version was co-produced and distributed by Canadian production company Catalena Productions (Rhodes Productions was the U.S. distributor). The 1984 daily syndicated version was distributed by Telepictures. One episode of the show was part of the summer replacement series Gameshow Marathon on CBS in 2006, hosted by Ricki Lake.
