So excited about it! Now we have a date: July 25th, 2010 on AMC

AMC has renewed Mad Men for a fourth season. No deets were released about how much more we’ll get or when it will air, but 13 episodes in the late summer of 2010 is probably a good guess.

The Emmy- and Golden Globe-winning series is set in a Madison Avenue advertising firm and tracks the rise (and fall?) of the American empire in the 20th century through the personal and professional life of “mad man” Don Draper.
