I went back to the FCC financial reports from the late 50's and early 60's. Back then, stations had to file complete financial data and report profits or losses.How many terrestrial stations have filed for bankruptcy in the past decade? Have you noticed how commercial radio licenses have lost so much value in the past 15 years?
Half the US stations in that era were not profitable.
Since then, the FCC has licensed more stations than the rate of U.S. economic growth could justify. Consolidation in the mid-90's was due mostly to the disastrous effect of Docket 80-90 with severely overpopulated the FM band nationally with no revenue improvement.
Nothing new and your point is not valid.
And the average vehicle in the US is over 12 years old. Current car sales would project that it will take more than a decade to get Bluetooth into just half of all cars.Or what about the fact that just about every new vehicle in the market has Bluetooth as a standard feature?
