The fledgling network continues to add new cities to its roster along with real advertisers such as Walgreens and Kay Jewelers (instead of public service announcements). Experts say its Internet presence -- drawing as many as 80,000 listeners an hour at http://www.airamericaradio.com-- is unparalleled. "Air America is far bigger than any other radio network's presence on the Internet," said Kurt Hanson, editor of RAIN, a radio and Internet newsletter. "It is the biggest success story for a U.S. broadcaster to date." All other successful broadcast enterprises have achieved their success over the airwaves, not dial up telephone lines. Who are these people trying to kid?
