And I think this is the lie that large corporations wish you to believe; namely, that large privately-held corporations whose primary interest is creating profits for their executives are providing a public service through economies of scale. The money that most of these corporations earn from selling advertising time and other business decisions primarily goes to the stockholders (through dividends) and to the corporate executives (through both executive pay and stock options).
Dividends also help boost returns for 401(k)s and pensions. Most people are stockholders without realizing it.
In the world of communications, we are giving people what they want to hear and not necessarily what they need to hear.
That's actually one of the tensions at the heart of journalism: sometimes people don't want what journalists are serving. "This will be good for you" isn't that much of a winning argument. Moreover, radio broadcasters, particularly program directors, have been working hard for more than four decades to denigrate the notion that radio is a public service or has any kind of public service obligation whatsoever. It would require an equal amount of time to reverse that, and it's not going to happen. The Internet, once it was commercialized, developed no concept of such obligations. Over-the-air radio and TV developed when content and transport of that content were packaged together, utilizing scarce spectrum. This provided the legal basis for regulation. The Internet is merely transport; content (and any platform) that rides on that transport can take advantage of much greater capacity. That's where the "net neutrality" arguments come in, but they are focused mostly on the "last mile" of individual connections to the broader network and ensuring that they are not throttled for commercial or political advantage.
There is no lie. Commercial radio's only source of revenue is advertising. Advertisers want media that can reach the most people. Format radio is reaching smaller and smaller groups of people because of splintered tastes in content. You see that in the ratings, where a 5 share is good enough to be #1. A 5 share is too small to satisfy advertisers. The only way radio can reach the same number of people is to own more stations that would allow them to offer more formats with less duplication. Meanwhile, there are no limits on the number of stations on the internet. People want more choices, and the only way to give people more choices is to allow companies to own more stations.
That said, let's look at what happens when companies get big. They become bureaucratic, averse to innovation, and sluggish. Good executives realize this, and take actions, sometimes harsh actions, to try to avoid it. That's what Jeff Bezos talked about through his concept of "Day One". That's why Jack Welch laid off so many people. Bezos was trying to keep a bureaucratic mindset from insinuating itself into Amazon; Welch was trying to reduce the influence of that mindset at GE (though he and Jeffrey Immelt fell into the traps of financial engineering, but that's another story).
For two years in the late 1990s, I had a front-row seat into a mass-market company whose business was in decline and just could not seem to correct its course: Sears. (I was at headquarters, not in a store.) Many good people, many good ideas, but poor leadership. It was a good education in how not to do some things.
iHeart, for one, has gotten big and bureaucratic, seeming to have vice-presidents stockpiled against the day that they might have something to do. But they need to cut costs, pretty much continually. Where do they cut? Mostly, it seems, at the front lines of people actually creating content for an attention economy and people who sell that attention ("commercials") to advertisers. That's the big-company mindset.
If there's further consolidation, expect to see more of that rather than less. Then, in a few years, the big companies may break themselves apart "to unlock value". Only the investment bankers and lawyers will profit.
So, essentially, removing ownership restrictions will be welfare for investment bankers and lawyers and a few top executives.
That's not to deny that over-the-air radio has what I call "structural problems": it's a mass-market, time-locked medium at a time when markets are fragmented and specialized and people want what they want when they want it. People who grew up and understand instinctively this new environment will be the ones to figure out the role of over-the-air radio. Government regulators won't; the best thing they can do at this point is just leave things alone.
