Comics Worth Reading has put up an article about all the ways Watchmen is being promoted now.

You can now enter to win a trip for two to the Watchmen premiere in Los Angeles, become a Watchmen mobile member and receive text updates on your phone, and older dvds are being reprinted with special Watchmen coupons inside.

Also, the animated Tales of the Black Freighter is being released March 24 to continue to promote the movie.
