Just look at what other countries are doing right and copy that. More concrete: Vote for a politician who will force the FCC to create a real market, not a oligopoly of a few large behemoths.
Contrary to most the promises politicians make, this one costs no money and simply involves signing the right bills into law. It will even be good for the economy. Of course, they would have to withstand the rich and powerful lobby of said behemoths, which is of course why such a politician will be very hard to find.
