(01.05 HC) Tuning in Teens: Businesses Intensify Pitch fоr 'Sаvviest Generаtiоn Ever' by Dаve Carpenter © 2012 The Assоciated Press (CHICAGO (AP) Murmurs of excitement rippled through the large hotel conference room when the eight special guest panelists filed in. Empty chairs filled and doorways crowded with onlookers. Cell-phone chats ended abruptly. Spectators leaned forward, eager to catch every word. These were no ordinary panelists to the officials of clothing companies, food giants, media dot-coms and others attending the marketing conference. They were American teenagers, articulating the consumer habits of a group projected to spend a staggering $155 billion this year. So they applauded the answers of these Chicago-area high school students, laughed at every attempted joke and flooded them with questions for an hour: Where do you buy things? What books do you like? What's your favorite band? Do you prefer TV or the Internet? For these teens and others, the interest in their world by grownups is appreciated. "It's nice to know my opinion is being paid attention to," says Silena Dukes, 16, of Bellwood, Ill., who wasn't on this panel but is nonetheless a contributor to intensifying market research into what makes teens tick. "It's pretty cool." As Americans' unprecedented prosperity filters down to the next generation, attracting teens' business has become a Holy Grail for marketers. "It's a very influential market," says Selina Gruber, president of Children's Market Research Inc. in New York. "Marketers never really paid that much attention to kids, but now they do because it's becoming their bread and butter."
