National spot radio up 17.7% in 2010 ...

From RBR:

National Spot Radio bounced back with a strong year in 2010, following a dismal 2009. The 17.7% increase was driven by strong demand across auto, telecomm, retail, consumer products, entertainment and the active political season in the run-up to November’s elections.

At the start of this year, National Spot is flat in Q1 compared to the same period last year, based on current Katz Radio Group pacing data. There’s been some negative effect on business in the quarter caused by major weather disruptions in major media markets and January revenue finished lower than last year.
