How? This is a serious question. Laying cable/fiber is tremendously expensive and is a natural monopoly. At best competing providers must lease infrastructure. So how does government induce "competition"?
I moved into a brand new subdivision and I had a choice between AT&T fiber and Comcast. It's also ranked as one of the 25 most affluent counties in the U.S. I'm not bragging, any senior software developer making an average salary in the city could easily afford a house here.
On the other hand, in some parts of the state, they use to have a choice between low data cap cable and even lower capped DSL. But AT&T doesn't even offer DSL in some places that they use to. They either pulled out the market or are not accepting new customers.
Make it easier to get right of way to lay cable for internet. Also state governments are making it illegal for counties to offer municipal broadband. The government gives incentives for everything else, why not internet service?
Google is offering service in limited areas of 8 cities and have put on hold any future expansion. That is not comparative to the rest of the country and shouldn't be used as an example of competition. The country has no real competition for internet service providers.
But AT&T seems to be being more aggressive about their Rollout between DSL (slowly dying), and their newer fiber offerings.
