Mad Men is taking an extremely long break after the end of episode 7 on May 25.
That break is confirmed to be until 2015.
No re-start date has been officially announced but we can take an educated guess.
First, season 7 started on April 13. So it’s highly possible that the second part of the season will start right around that time next year.
The other key piece to look at is Breaking Bad season 5, because the Mad Men schedule is based on that.
Part 1 of that season started on July 15; part 2 started on August 11.
So it’s even possible that part 2 of Mad Men season 7 will start sometime in May, meaning the wait could be almost an entire year.
