NBC uses Twitter to launch \'Grimm\'

NBC is giving Twitter users a sneak peek at one of its new fall series. Two weeks before the drama "Grimm" debuts on NBC, the network is making the first episode available to those who follow the show handle on Twitter. Starting Friday, those people will receive a direct tweet with access information to preview the Oct. 28 premiere episode of "Grimm" (9 p.m. EDT). NBC will also be screening the episode in 10 cities nationwide, starting Tuesday in Los Angeles and including Portland, Oregon, where "Grimm" is filmed. Some of the show's producers and cast members will be on hand for the Los Angeles and Portland events. Showings are also set for Chicago, Philadelphia, Washington, Denver, Atlanta, Minneapolis, Phoenix and Seattle. NBC Entertainment Marketing President Len Fogge, who announced the campaign Friday, said it's a unique approach that matches the nature of the drama.
