Jay Stewart previously announced for Let's Make a Deal from 1964-77, and later went on to announce for Sale Of The Century from 1983-88 and Scrabble from 1984-86. Incidentally, original Deal host Monty Hall previously worked for Barry & Enright as host of Twenty One during the Summer of 1958.

Only two episodes of the NBC nighttime version note (April 3 and December 22, 1958) and the first four episodes of the CBS run note (July 3-6, 1978) circulate. Some Barry episodes are available for viewing at the Paley Center for Media in New York.
Of the 1978-86 nighttime run, GSN has never showed anything from 1980-83 along with the tail end of the final season.
The 1990s version reran on USA from 1993-94, but hasn't been seen since.
What Could Have Been: There would have been a Syndicated version no matter what, and it would have aired alongside the daytime one, when production began in June of 1978. But when the daytime edition fizzled a month later, production immediately switched over to the Syndicated edition. Tapings lasted at CBS Television City (using Studios 43 and 31) from June 1978 to December 1980 (2/3s into season 3). Production then moved to KCOP-TV for all but the 1984-1985 season (there, they were at The Production Group Center)
