The fourth season of Mad Men comes out on DVD today, and fans are encouraged to pick it up. Why? Because it will be your last chance to watch Don Draper and company for a long time.

Due to a contract dispute between AMC and creator Matthew Weiner, the fifth season of this beloved drama won't return until 2012. The network itself announced this fact via the following statement:

"While we are getting a later start than in years past due to ongoing, key non-cast negotiations, Mad Men will be back for a fifth season in early 2012."

Pour yourself a scotch and take a cigarette drag, fans. It's gonna be a long year.
