Bill Nye the Science Guy made learning science fun with his show, which hit the airwaves in 1993 and has been gathering a following ever since.
But how did this former Boeing engineer become one of the most famous science figures in the United States?
Bill Nye joined KING 5 Morning News on Friday to talk about how he got his start inspiring new generations of scientists.
"It's really gratifying," Nye said of the show's success. "The goal was to make the show so self-contained, so compelling that teachers would use it in school."
Bill Nye has a new app out to mark the show's 20th anniversary, available in the iTunes Store.
