"Let's Make a Deal" first aired on NBC in 1963 as part of its daytime schedule. The show moved to ABC in 1968, where it remained until 1976; and on two separate occasions the show was given a weekly nighttime spot on those networks. The first syndicated edition of "Let's Make a Deal" premiered in 1971. Distributed by ABC Films, and then by its successor Worldvision Enterprises once the fin-syn rules were enacted, the series ran until 1977 and aired weekly.
