Just read this in yesterday's edition of the Lund Letter (many thanks to Joel Swanson for recommending this resource!):
"Because of the erosion in TV’s audience at the hands of DVRs, Netflix, and wholesale avoidance of commercials, the Southern California Broadcasters Association is recommending a 39% shift of dollars from TV to Radio in the Los Angeles area. The factors they cite are true nationwide. You may wish to look at their presentation here to gain ideas for your approach to TV dollars."
Very thorough report. Believe this information is probably applicable anywhere in the country. I especially liked the charts showing commercial skipping. That's a lot harder to do listening to the radio for sure.
