Bitten by auto correct. And your assumption is correct.
Because, as we are seeing, terrestrial radio is in severe decline with reductions in everything from news coverage to live talent. The reason is that, in inflation adjusted dollars, radio is off 60% in revenue since 2005. This means that the "profit window" is gone right now with the Corona Virus making it even worse.
The problem is that free streaming can not currently be profitable because of the digital rights fees and the reduced buying of advertiser sponsored media. So we will have some kind of transformation in the model of terrestrial broadcast radio to adapt. My suspicion is that we will see "national" radio with local stations just repeating national formats, such as what we see in much of the rest of the world.
As BigA said, the predominance of different ad categories is due to the absence of conventional accounts. Stations are taking anything that comes along since, as we have seen from the Q2 financial reports of the public radio companies, all radio is losing money.
Interestingly, in talking with some friends who own very small market stations, they report that revenue is not off by the 30% to 60% seen in bigger, rated markets. It almost seems as if the bigger the market, the more damage has been done in the pandemic. Part of this, of course, is that the bigger markets have much higher agency business and the agencies are not buying as much, and they are not buying radio under the belief that new media is a better vehicle during the pandemic.
Most of the smarter radio groups are tying to move the whole business model to online, leaving AM and FM behind or as a supplement only. But that means that listeners have direct expenses of needing online service providers and optional expenses for subscription services.
