We all love talking about how there used to be three channels. Things were so much simpler back then! Cronkite was a newscaster we could trust, and we didn't get bogged down by the hundreds and hundreds of choices.
But can you tell those three channels apart? Do you know ABC from NBC? How about NBC from CBS?
We'll name a show, and you tell us which network originally aired it! Good luck, and be sure to share your score in the comments section below.
