It looks like wiser heads--or at least those who could be made to recognize a great PR opportunity--have prevailed at AMC.

If you're one of the many hooked fans of the cable channel's hit show, Mad Men, which chronicles the goings-on at a fictional 1960s New York ad agency, and you're also a Twitter user, you might have found yourself eagerly following tweets from folks like Don Draper, Roger Sterling, or Peggy Olson.

And getting people to follow the show's characters probably seemed like a clever way of using Twitter for marketing.

Except that AMC had nothing to do with it. And after discovering that somebody out there in the badlands of the Internet was appropriating its characters without permission, the network filed a DMCA takedown notice with Twitter, forcing the microblogging service to suspend the accounts.

Which, if you think about it, doesn't make a lot of sense. Why would you stop someone from driving interest in your content, especially when they're doing it for free--and not damaging your brand?

Surely there are some copyright issues that AMC's lawyers were worried about, and indeed, I'd be very interested in knowing what those issues are.

But according to Silicon Alley Insider, AMC has decided, after being "gently nudged" by its Web marketing agency, Deep Focus, into changing its mind and letting Twitter reactivate the accounts.

And by "gently nudging," I hope they mean they screamed and yelled and threatened to quit if AMC didn't see the value of letting fans promote the show on their own.

Either way, it's good to see that Draper, Sterling, Olson, and other show characters are once again letting us know about their latest comings and goings.
