The Price Is Right and To Tell the Truth, both created by Stewart, are the only game shows to be seen nationally in either first-run network or syndication airings in the US in every decade from the 1950s onward.

In the book The Box, the native New Yorker said he got the first spark for The Price Is Right during his tenure as a staff producer at WRCA-TV (now WNBC-TV) when he happened to observe an auction taking place on 50th Street on his lunch hour.

CBS' To Tell the Truth, emceed by Bud Collyer, hit the air less than one month after the original Price debuted, in December 1956.

Stewart said he auditioned the concept to Goodson and his producers by trying to have them guess which one of three men had been in the infantry in World War II and was now managing a grocery store.

Producers such as Stewart, Frank Wayne, Chester Feldman, and Gil Fates earned Goodson's respect not only for their concepts but for their skill in executing them.

Stewart's next entry, the CBS primetime celebrity game show The Face Is Familiar with host Jack Whitaker, ran from May 7 to September 3, 1966.

Other than Eye Guess, Stewart's other moderate early success was Three on a Match, hosted by Cullen, which aired on NBC from August 2, 1971 to June 28, 1974.

Its March 26, 1973, premiere on CBS marked the biggest possible cash payoff on a quiz show since the short-lived 100 Grand in September 1963.

(premiered in 1984 with Alex Trebek as host until October 29, 2020 tapings, and currently Ken Jennings since 2021), which has 19 wins (combined daytime and primetime).

Another version of Pyramid, packaged by Sony, which now possesses the rights to Stewart's shows, aired in syndication from 2002–2004 hosted by Donny Osmond.

Pyramid nearly led to Stewart's one significant foray outside the world of TV games, when he was hired to produce occasional panelist David Letterman's NBC daytime show in 1980.

Coincidentally, during the first half of 1980 the company's New York-based Pyramid on ABC was competing in the same 12:00 noon (Eastern) time slot against its Los Angeles-based Chain Reaction on NBC (both shows were cancelled in June of that year).

Other Stewart productions, mostly employing a word or puzzle format, included Winning Streak (1974–75), Blankety Blanks (1975), Shoot for the Stars (1977), Pass the Buck (1978), Go (1983–84), and Double Talk (1986).

and Chain Reaction produced for the USA Network on cable during the mid-1980s were videotaped in the Canadian cities of Toronto and Montreal, respectively.

Stewart, a native New Yorker, had resisted the move because he appreciated the intelligence and energy contestants from the city brought to Pyramid and his other shows.

A revived Chain hosted by Dylan Lane and produced in New York by Michael Davies ran on GSN for two 65-episode seasons from 2006 to 2007.

Sande later produced some game shows on his own, including Your Number's Up, which went up against the elder Bob Stewart's Pyramid, Remember This?, Sports on Tap, Inquizition, Hollywood Showdown, Missouri Lottery Fun & Fortune, The Oklahoma Lottery Game Show and Powerball Instant Millionaire.
