The beta testing was done on CBS-owned modern rock “Live 105” KITS, San Francisco, and now CBS adds the feature to its Las Vegas modern rocker, “X107.5” KXTE. Jelli, distributed by Triton Media, offers listeners a catalog of tunes online and encourages them to either vote for it (giving it a rocket) or against it (a bomb). Even when it’s playing on the air live, they can say it “rocks” or “sucks”, and if it gets enough negatives, it’s pulled off immediately. Kirk Stirland, president of programming at Triton Media’s Dial Global syndication unit, says there are two versions for affiliates – Rock Jelli and Pop Jelli. Early signups include Greater Media’s modern rock WBOS, Boston (92.9) and Nassau’s hot AC WPST, Trenton-Philadelphia. Jelli CEO Mike Dougherty says crowd-sourcing lets radio participate in the “cultural transformation driven by the social web, giving a new voice to millions and millions of consumers.”
