''Mr. Wizard's World'', a faster-paced version of the show, was shown three times a week on [[Nickelodeon]], the then-rising kids cable channel. Once again, the revival was produced in Canada (this time in [[Calgary]]). It produced 78 episodes from 1983 onwards, and continued to run thereafter as reruns. During its run on Nickelodeon, it was the channel's #3 rated show in 1983 (behind ''[[Livewire (talk show)|Livewire]]'' and ''[[You Can't Do That on Television]]''). It was also famous for its ''Ask Mr. Wizard'' segment where Herbert answered questions sent in by viewers of all ages. Episodes of this version of the show were reaired in 2005–06 on the digital cable channel [[The Science Channel]].

Herbert once said: "My time on this Earth is getting shorter and shorter each day, but no matter how old I get, and even when I am dead, ''Mr. Wizard's World'' will never die". It was canceled in 1989, though reruns continued on [[Nick at Nite]] until 1995 and often in early morning time slots right after Nick at Nite finished (usually as part of [[Cable in the Classroom]]) until August 2000. In 1994, Herbert developed another new series of 15-minute spots called ''Teacher to Teacher with Mr. Wizard''. They highlighted individual elementary science teachers and their projects. The series was sponsored by the [[National Science Foundation]].

Selected episodes of ''Mr. Wizard's World'' are available on DVD from Mr. Wizard Studios Inc. in ten single volumes featuring four episodes on each disc. Gift box-sets are also available. Five seasons of the show, 75 episodes of the 78 total were released on Amazon instant streaming.<ref>{{cite web |url=https://www.amazon.com/gp/product/B00NL5PPW4 |title=Mr. Wizard's World, 5 Seasons |website=Amazon |access-date=2014-12-27 |year=2014 }}</ref> These episodes are also available through Vudu and can be streamed for free with ads or rented for a fee.<ref>{{Cite web|url=https://www.vudu.com/content/movies/collection/content/Family-Kids/25135?minVisible=21|title = Vudu - Watch Movies|website=Vudu.com}}</ref> [[Paramount Global]], the parent company of Nickelodeon, has also added the series to its [[Pluto TV]] service.
