Dueling Shows: With The Price Is Right, to an extent. Deal had games in which contestants had to guess the prices of grocery items. When Price returned to the air in 1972, it was reformulated to include similar games. Mostly averted now as both shows appear on the same network, although Deal no longer has the pricing deals to avoid being too similar to Price.
Franchise Killer: Outright averted with not only the 1990 revival, but also FOX's Big Deal (1996) and the 2003 revival for NBC. The former was hosted by the inexperienced Bob Hilton, and failed so badly that Hall returned to host the tail end of it in an attempt at an Author's Saving Throw. The latter two lasted six and three episodes, respectively, these revivals had obviously transparent attempts at being "hip" and "edgy". The fact that the Brady version began Season 5 in 2013 shows that the three revivals before it were not detrimental.
Averted with Monty Hall, as this is pretty much the only thing he's known for. While the man did host several other games (It's Anybody's Guess, the 1979-80 Beat the Clock, the 1986-87 Split Second), none were nearly as prolific.
Dennis James would later become famous for a nighttime syndicated version of Price, which was both his longest-running game and his last. Despite this. the effect it had on the show's popularity, and the fact that it was in development long before CBS became interested...James' Price has become rather obscure.
Bob Hilton was being considered to replace Johnny Olson on Price, but turned down that opportunity to host two pilots. note (Fun For The Money and Bamboozle, the latter of which was an Expy of To Tell the Truth to the point where Mark Goodson slapped Chuck Barris with a lawsuit.)
Billy Bush is the host of Access Hollywood and a cousin of George W. Bush.
Ricki Lake had a self-titled talk show.
Wayne Brady is best known as a regular on the American Whose Line Is It Anyway?, which was hosted by Drew Carey (who currently hosts Price).
The original NBC series appears to be mostly gone. The 1963 pilot was aired by GSN as a standalone special in 2003, while a few 1960s episodes (including one from 1965 and two from '67) are held by the Paley Center for Media. A few silent color clips of a 1966 episode surfaced in May 2013.
The 1980-81 version is also pretty rare, with only three episodes known to be around. The 1990-2003 versions haven't been in reruns at all.
Hall wanted to move the show elsewhere after NBC balked at the idea of putting a nighttime version on its regular schedule, despite a nighttime version in Summer 1967 consistently beating its competition.
The ABC version was screwed by the network's attempts to boost ratings by having the show offer huge prizes and go to an hour-long format. When this failed, the show was moved on December 29, 1975 from 1:00 PM to Noon — against High Rollers on NBC and local programming on CBS. Despite initial success (forcing Rollers to 10:30 AM and defeating its replacement, the return of The Magnificent Marble Machine), Deal fell on July 9, 1976 against The Fun Factory.
The 1990s version was originally hosted by Bob Hilton. Hall replaced him as "guest host", with the intention of eventually doing a series of on-air auditions, then picking one of the candidates to host the show on a permanent basis. NBC had other plans, and canned the show outright.
Big Deal had far too many things going against it to list here, the least of which was being slotted right after NFL games...which tend to go overtime.
The 2003 run had an unproven host (Billy Bush) and several skits that smacked too hard of trying to be "hip" and "modern". Then, on the last aired episode, a one-deal appearance by the Big Dealer himself made Bush look like a total imbecile. note (Nothing against Bush or any other host, though — Hall is just that good at making a very complicated job look easy.)
Talking to Himself: In the two deals below, Dean Goss is hosting and announcing at the same time, but according to the comments his announcing was pre-taped.
What Could Have Been: During his year as announcer, Goss hosted twodeals with Monty appearing in a cameo. Goss said in a later interview that these deals were done on purpose — had that version been renewed, Monty would've passed the torch to him on the season premiere.
