Regardless of your age or gender, Gossip Girl has something that appeals to youbetween the show's dramatic characters, the sometimes convoluted plot, the unique music and the gorgeous fashions, there's a little something for everyone. But there's no arguing that GG has succeeded in building a die-hard fan base of young "tween" girls whose passion for TiVo-ing the show or downloading it on iTunes led to it being the first new fall series to be picked up for a full season. These girls are a movement in and of themselves, and they've got a surprisingly strong grip on the economy. Leighton Meester stars as Blair Waldorf in Gossip Girl.
