Google announced plans yesterday to test out ultrafast gigabit broadband in limited markets. // The goal is for Google to demonstrate what is possible. By choosing some test markets and implementing broadband 100 times faster than that being delivered by most broadband providers currently, Google can prove that it's possible, and back it up with real-world results and project costs.
In theory, broadband providers like Comcast and AT&T are already aware of what is possible. But, broadband providers are interested in what's profitable more than what's possible.
