The service was unveiled in December 2012 and has circulated to a very limited number of cities throughout the States, though as the project is developing the increase rate of candidates will grow respectively.

As of March 2015, Google stated that 27,000 people from the three areas that Fiber is available have subscribed to it. These three areas are Austin, Tex., Kansas City, and Provo, UT. Fiber retails for US$70 per month.

Google’s website for Fiber offers a handful of information regarding plans and availability, while visitors can check if their address is eligible for the service. Moreover, the web page provides an app where people can see how Fiber stands out compared to the rest standard internet speeds, by conducting a series of tests.
