His first production for his independent company was the game show Eye Guess that aired in 1966 and was co-produced by Filmways and lasted until 1969.
In 1973, he created the successful Pyramid game show series starting with The $10,000 Pyramid with his son Sande Stewart who joined his father the same year and produced the series and also formed another production company Basada, Inc. on 23 February, which was named after his sons: Barry, Sande, and David Stewart.
In 1978, Bob Stewart Productions was relocated to Los Angeles, California, with its first syndicated program at its new location, The Love Experts.
Another game show was Go, that was based on the bonus round of Chain Reaction produced alongside his son, Sande one year later.
They were Pyramid and was hosted by Donny Osmond in 2002 for syndication and Chain Reaction in 2006 produced by British television producer Michael Davies' production company Embassy Row in association with and distributed by Sony Pictures Television aired on GSN and was hosted by Dylan Lane.
Pardo was an announcer on most of the Stewart productions that originated from New York for NBC (examples are Eye Guess, Three on a Match, Winning Streak, and many others).
One of the other longtime employees was a close friend to Bob Stewart; Bill Cullen, who has hosted the syndicated version of The $25,000 Pyramid among other series: Pass the Buck, Blankety Blanks, Winning Streak, Eye Guess, Three on a Match, The Love Experts, and the 1980 version of Chain Reaction.
Francine Bergman and David Michaels were associate producers of most of Bob Stewart's 1980s game shows.
Sony Pictures Entertainment owns the entire Bob Stewart Productions program and format library.
Many episodes from that era are preserved by home recorders and network/syndicated affiliate employees which surreptitiously either dubbed off, or retained bicycled copies, and exist mainly through tape trading and gray market uploads to video sites.
