U.S. commercial radio revenue was off 6% in November, compared to the year earlier.
The RAB reported this week that local revenue fell 5%, national was off 15% and non-spot was up 14% in the month.
The report suggests a weaker ad market than radio had already been experiencing. The most recent quarterly report from RAB, issued in early December, showed revenue for the first nine months of 2007 off 2% overall.
