If you need a TV fix to get you through the repeat season and “The Singing Bee” just ain’t cuttin’ it, try this new gem straight from Madison Avenue: “Mad Men” premieres July 19. Set at the fictional Sterling Cooper ad agency in 1960, the show glamorizes the glorious golden age of advertising. The AMC series–created by “Sopranos” writer Matthew Weiner–takes us back to a time when secretaries performed more than clerical work, smoking in meetings was required and lunch was three double martinis. And the clothes! We love the clothes. More clips here.
