Ad revenues at America's radio stations have fallen for the first time since March, according to the Radio Advertising Bureau.

The RAB recorded a 1% year-on-year dip in October advertising, only the second decline of 2003 so far. National ad revenues climbed 1%, while local advertising sank 2%.

For the first ten months of the year, total radio adspend increased 2%, reflecting a 7% surge in national income and flat local revenues.
