In radio this is called Payola where record companies pay to get their records played. It's illegal. There were congressional hearings about it in the 50's and 60's. It continues to this day.
Now the "business model" of paying for content delivery is legal. And there is no limit on campaign spending. Guess what will happen in the next election?
No major news outlet will report when news conglomerates up their rates for political programming so only big players will be able to afford airtime. Remember cable/broadcast/newspapers are now single corporate entities, and money talks.
How long will it take for differential pricing to drive Al Jazeera off the air? Remember they're just a bunch of terrorists! The same for RT (Russian Television) and any non-US centric new outlets as well. I expect NHK will be OK because they will self censor perceived criticism.
Expect the political programming on PBS to disappear as well. Remember that they criticize Corporate America, and it's Bad for Business. Don't worry, you'll get to keep Nature, NOVA and Antique Roadshow. Keep sucking on that pacifier.
Ever notice that PBS NOVA gets "major funding" from the Kock (pronounced COCK) brothers? When was the last time NOVA did a program on global climate change? Sound of crickets...
Welcome to Plutocratic America. No democracy, no free press, no capitalism. Nothing to see here, just move along.
