From the Official Google Blog:
We’re planning to build and test ultra high-speed broadband networks in a small number of trial locations across the United States. We’ll deliver Internet speeds more than 100 times faster than what most Americans have access to today with 1 gigabit per second, fiber-to-the-home connections. We plan to offer service at a competitive price to at least 50,000 and potentially up to 500,000 people.
Even if Google’s service doesn’t make it to everyone, I hope it at least convinces companies like Comcast and Time Warner to finally upgrade their infrastructure.
