Local did worse than national business, says New York-based Kantar, down an estimated 20.3% for the full year and 11.7% for the fourth quarter. National spot shrank nearly 25% (24.6%) for the year and about 17% for Q4. Kantar’s estimate of network radio business is that it dropped about 8-9% for both the full year and Q4. Radio’s estimated total take, therefore, was off about 20.3%. For purposes of comparison, Kantar believes all television media combined dropped about 9.5% last year, outdoor was off about 13%, newspapers fell about 19.7% and Internet display ads improved by about 7%.
