Here’s a good one. I happened to notice this phrase, “meaning of mad men,” showed up in the search terms for the blog (that is, someone searched on that phrase and ended up here). So I thought that was worth defining. It was explained in caption text at the beginning of the first episode, but of course, many viewers have joined the Cult of Mad Men since then.

In the 1950s and 1960s, the advertising industry was based on Madison Avenue in New York City. In fact, “Madison Avenue” used to be slang for “the ad industry.” Madison/ad men was contracted into “mad men” (no women, of course) by the mad men themselves.
