Clear back in 2011 Google announced it's project "Loon" and said that they were going to use baloons to deliver internet from the sky in order to enable more people to get internet access. This seems like a lofty goal (pardon the pun) and the real reason is that when more people use the internet, they will likely use your services. Facebook announced last week that they are buying Titan Aerospace and will also be competing for your internet connectivity. Facebook will be using drones instead of baloons and the real reason they are going with drones is so that they can burst Google's balloons. Don't believe me? It will happen.
There is actually a long history of failed attempts to provide aerial internet access. Starting in the 1990s at least five big projects were announced, including Iridium and Globalstar, both of which aimed to provide cellphone coverage. They were actually built but promptly went bankrupt. Teledesic, a venture funded by by Bill Gates, Paul Allen, and Saudi prince Al-Waleed bin Talal, got a lot of people interested but was scrapped before it launched its first constellation.
