Regardless of the amount of TV i watched, i NEVER could remember the difference between ABC, CBC, and NBC. It was always just channel numbers. I missed 6. Two CBS, one ABC, and three NBC. I got all of the others haha.
I only legitimately knew the answers to about a dozen of these but somehow guessed my way to 19. Luck ran out on General Hospital. Knew it had to be one of the major broadcast networks but couldn't pick the right one.
