Watch Mad Men Season 4 Episode 7 Online

The American cable drama is TV land's most seductive show in years. It's also fast becoming one of its most bankable. Sex sells but, apparently, so does the art of selling itself, set, as Mad Men is, in the world of advertising. Such is the show's cult status that BBC4 decided to hurry along season four in an attempt to protect its ratings from piracy and help viewers dodge the spoilers clogging the blogosphere and twitterverse.
