OK,I'll bite.
In the USA,technically the license is owned by the government granted to the licensee. The licensee is allowed to program the station to their preference. Advertisers have some indirect influence if you consider programming is typically fine tuned to reach as many as possible to increase the odds of advertisers choosing the station as an advertising venue. The FCC makes no decisions on station programming except where FCC rules are concerned. In my decades in radio we have never allowed any advertiser to influence programming content regardless of how much they spend and any suggestion from an advertiser about content would be considered hostile and unwelcome.
Radio programmers back up all that they do with documentation from others or better yet local market research the station itself conducts.That's a far cry from stupid. The programmer keeps their job through successful programming that delivers the listeners.
Radio advertising rates are based on the number reached with the message. Some Low Power FMs charge pennies.
Fascist? Radio stations, in the USA, program for listeners. Thus, programming reflects the wants and desires of the target demographic the station has chosen for it's audience. If Fascist, there are lots of Fascists out there.
Radio is a government monopoly in many nations. In many of those countries there are tons of pirate stations. In nations where radio is government owned, radio listening is nowhere close to as popular as radio is in countries where radio is licensed to private companies.
I believe radio will mainly become national in coming years. I base this on the nature of most radio being reliant on local businesses for revenue. With national chains and online shopping adversely affecting local station revenue (more pronounced in smaller markets) by leaving the local merchant with fewer advertising dollars to work with, it only makes sense for national formats to take over. It may not be a satellite feed but certainly many elements would be identical.National shows have proven popular even in music formats.
