The upcoming movie “Hunger Games” has taken social media marketing to a whole new level. As reported by Brooks Barnes in the New York Times: “Selling a movie used to be a snap. You printed a poster, ran trailers in theaters and carpet-bombed NBC’s Thursday night lineup with ads. Today, that kind of campaign would get a movie marketer fired. The dark art of movie promotion increasingly lives on the Web, where studios are playing a wilier game, using social media and a blizzard of other inexpensive yet effective online techniques to pull off what may be the marketer’s ultimate trick: persuading fans to persuade each other.”
