Yesterday, to be exact. Rich Sommer (Harry) is Twittering about it, and Variety has a story.

The Variety piece says that AMC has "delayed" the show until August 16, but I don't think it's really a delay since the show just started filming this week. Who wants them to rush things? Sure, it's a month later than usual (the show usually premieres in July) so I guess it's a delay, in general, but contract negotiations with Matthew Weiner and other things factored into that. It's still pretty much on target with its season opener, though the show will now go even deeper into the regular seasons of the major networks. The show remains in its Sunday night at 10PM slot.
