When I was very young I watched a fair amount of black and white TV shows in the 1980s. (I had a fondness for Car 54 and Dennis the Menace on Nickelodeon). I somehow came to believe that television was always recorded in color ad that the whole world used to be black and white.
Apparently I had gotten the idea from a Dennis the Menace comic (I used to read it everyday, but Sundays inparticular). In one comic Dennis asked his father why TV was in black and white and his father tells him that the whole world was black and white. I was too young to realize this was the joke of the comic.
Still that would be interesting now wouldn't it? :-)
