How Google Fiber changes the cities it's chosen

Even though Google Fiber is expanding slowly, the service is having an effect in lots of other cities. That’s because existing providers such as Comcast and AT&T are rolling out their own super-fast Internet services in cities where Google Fiber is being built, or where Google is rumored to be considering a build. Google doesn’t have the resources to roll out fiber service in every city that wants it. But the growing number of Google Fiber installations shows that there’s a demand for super-fast Internet, and it puts competitive pressure on incumbent providers to roll out their own fiber services.
