If you've never seen the show, I'd suggest you checkout Mad Men tonight (Sunday) at 10 p.m. on AMC with later viewings later in the week.
This is the beginning of the third season and it's a look at a New York advertising agency in the 1960s and also a look at what America was like when men were the executives, women were the secretaries, minorities were invisible, smoking and drinking in the office were common and the wives of the executives stayed home even if they had college degress while their husbands chased skirts.
If you were old enough to remember those days, the show will bring back memories. If you're too young to remember those days, you'll get a look at an America that no longer exists.
HBO to its regret passed on this show so you can see it on basic cable on AMC. It's worth a look.
