Google Fiber includes TV Google Fiber The launch of Google Fiber last week in Kansas City has left everyone asking about Google's plans to go nationwide with this game-changing super fast service.

Our suggestion is that people don't hold their breath waiting for Google's super-fast fiber network to come to their home.

To do Google Fiber in a big way would mean spending billions. If Google went head-to-head with Verizon Fios and built a network of similar size, that could cost $50 billion, says Internet analyst Rory Maher at Capstone Investments in a research note.

To do Google Fiber nationally it could cost $400 billion, Maher reckons. Plus, it would take years.

But there's no question that Google is ramping up to invest in Google Fiber beyond a single city. It's been collecting patents for fiber technologies. Plus Google is looking to hire about 30 people to its new Google Fiber team, including a bunch of new product managers.
