The highly anticipated sixth season of "Mad Men" returns to AMC Sunday night with a two-hour debut show.
"Mad Men" is known for its rave reviews and a cultural impact much bigger than its viewership—just 3.5 million viewers tuned in to the season five premiere. The show has repeatedly swept the Emmy Awards and it's drawn an incredible amount of press coverage.
It has also sparked a resurrection of a certain retro style—Banana Republic struck a deal with the show to sell the Mad Men Collection. Perhaps most impressively, it launched the renaissance of what was once a quiet basic cable network, AMC, and its parent company, AMC Networks.
