It was Nickelodeon's #3 rated show in 1983 (behind Livewire and You Can't Do That On Television). And also famous for its Ask Mr. Wizard segment where Mr. Wizard answered questions sent in by viewers of all ages. It then reran The Science Channel from 2005 to 2006 and still frequently airing on it. 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". 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.
