@lauren Yes. Mr. Wizard in the 1950's & 60's inspired many scientists and engineers (including me) some of whom got us to the moon. Movies, too, like Star Wars and iRobot co-founder Helen Greiner. As a child, she was inspired by the vision of robots like R2D2 in the initial 1977 Star Wars movie. R2D2 was just a facade, but Helen and her workmates brought the vision to life, with some robots autonomously cleaning living-room floors and others with human guidance defusing very real, deadly bombs.
@lauren My wife gave me a set of DVDs of those later programs. Some of my grandkids like watching them when they visit. I watched the original early ones as a kid getting up early Sunday morning on a B&W set.
Maybe more recently MythBusters inspired another generation. Now it could be Mark Rober. (Grandkids have been in to his stuff on their own.)
@danb Unfortunately, MythBusters over time degenerated into the "blowing stuff up show" and cannonballs into Dublin suburbs.
@danb Sadly, it would likely be impossible for many reasons to widely broadcast a program like "Watch Mr. Wizard" today. I still have a set of his books from the show.
