Google wants to give the world free internet
Google and Facebook are constantly trolling each other, and with Zuckerberg trying to give the developing world the internet (so they can keep tabs on absolutely everyone, ever), Google want to give the world free internet too (so they can keep tabs on absolutely everyone, ever).
The internet behemoth is rolling out free wifi in New York as part of a trial, which Google hopes will end up spanning the entire planet. They've set up a branch of their company to deal with this called 'Sidewalk Labs', are they're hoping that they can create a signal that everyone can use, so you don't have to rely on ropey connections in shops.
In New York, they've hit on a decent idea - they're turning a load (10,000 in fact) of old phone booths into 'wifi pylons', which of course, will be ad-supported.
As well as that, the converted booths will provide a point where you can charge up your mobile phone (you have to assume it'll have adapters that only work for Android phones, as Google inevitably won't want to help out Apple at all). The old phone boxes will also have a touch screen so you can get info about the city and transport, and you'll be able to make free domestic calls too.
These spots will be appearing in Autumn, and if they are deemed a success, Google will start rolling them out in other places.
