Top execs from five terrestrial radio groups recently talked about the challenges and the competitive factors facing the industry, according to Communications Daily.

But it's what Gary Stone, president of Univision Radio, said that interests me the most. He said that radio broadcasters need to realize they're competing against more than other stations for marketers' attention.

"I'm no longer in the radio business," said Stone, in front of a crowd of media buyers in Beverly Hills. "I consider myself to be in the audio delivery business, marketing multiple platforms to marketers."

'nuff said.
