Google's super-fast Fiber service has officially rolled out in Dorothy's backyard, in Kansas, but hasn't burst out of Kansas' gates and across the US just yet. But the question is, just how much would it cost to roll out the Google Fiber service across the entire of the US?

Well, according to the latest estimates from Goldman Sachs, it would come to the tune of around $140 billion. This is an incredibly huge sum of money, and while Google may be a huge and very powerful company - there aren't many companies who can just throw down $140 billion (estimated, it could cost much more than this) and rollout a Fiber network.

But, Google could roll it out in stages in bigger cities to see the reception from the consumers and continue from there. They could have a bigger 5-10 year plan where we see the super-fast Internet rolled out to all Americans.

Another benefit of Google Fiber is that it's instantly profitable once the customer is connected, unlike some of their other products. Would you like to see Google Fiber rolled out into your town, city or apartment block?
