When it comes to learning about your every activity, Google and their new parent company have lots of options. Between Search, what's left of Google+, Photos, Android, Chrome and Docs, plus the Nest product line, the company can easily learn a lot about your activities online and offline. The problem with all of this data collection is that it is indirect.
That is where Google Fiber comes in. Following your activities online are far easier when the company controls the entire pipe into your home. Hence Google Fiber's $70 1Gbit Internet plan. The price is not because Google loves you and your cable company doesn't; instead it is because the company loves your data. They can sell your Internet practices to advertisers and more than make up for the price difference between Fiber and FiOS.
This week, they announced plans to investigate moving in to 3 more cities: Irvine, Louisville and San Diego. According to the company,
We'll work with Irvine, Louisville and San Diego to conduct a detailed study of factors that affect construction, such as local topography, housing density, and the condition of existing infrastructure. Meanwhile, cities will complete a checklist of items-such as providing a map of utility lines-that will prepare them for a large-scale fiber build.
This will be an exciting development for those who do not mind the data retention policies of Google and have been asking for the company to bring their subsidized service to their areas.
