The Sega-Vision (not to be confused with the handheld Sega Vision system) was a US television set created by Sega. It was designed by Earl "Madman" Muntz in 1976, a businessman known for wacky television adverts and for coining the phrase "TV" in America. The Sega-Vision was notable for being significantly bigger than most TV sets at the time, and was Sega's first product meant for the home.
Aside from a US Patent and a TV commercial, very little is known about the Sega-Vision.
