In 1991, GPN released five episodes from the first two seasons on VHS ("The Problem of the Missing Baseball", "The Trial of George Frankly", "The Problem of the Dirty Money", "The Case of the Missing Air", and "The View from the Rear Terrace").

Around the same time, select PBS stations combined parts of an episode to air in primetime. This was done primarily for seasons 3-5 (New York City era), although at least one omnibus from the Leech era was also broadcast. These versions were re-edited so that they would come in at just under an hour long, featured other segments from ''Square One TV'' as "commercials", and newly created end credits, among other differences. Two of the primetime airings were also commercially released as VHS tapes from Republic Pictures in 1994 ("Despair in Monterey Bay" (retitled to "Treasure in Monterey Bay") and "The Case of the Unnatural").

Both ''Mathnet'' and ''Square One'' went off the air in 1994 (it was rerun until then after the final 1992 season was completed), reappearing from 1999 to 2003 on the cable television network [[Noggin (television)|Noggin]], a joint venture of [[Nickelodeon]] and CTW. However, only 65 episodes were leased by the Noggin network. ''Mathnet'' segments also aired on ''[[Phred on Your Head Show]]'' (one of Noggin's original programs).<ref>{{cite web|title=Square One TV Episode 211|url=http://www.tv.com/shows/square-one-tv/episode-211-210986/|work=TV.com|access-date=3 July 2012}}</ref>
