Against The Odds

The first season of Mad Men was set in 1960. This season it's 1962--the final episode takes place during the Cuban Missile Crisis. Overall there are five seasons planned (just like Star Trek, which can be referenced starting in season four), ending in 1968.

I've heard some fans complain the show will miss JFK's assassination. I disagree. Drama set with that backdrop has become a cliche Mad Men would do well to avoid.
