Commercialized GPS

This is another military technology brought to the masses. A space based series of satellites that connect together to provide accurate location detailing, it was developed in 73 so the armed forces could have better navi while overseas. It wasn t until 1996, though, that it became available to us civilians when Billy Clint issued a policy calling for a dual use GPS system. Fast forward to 2010 and navigation is a billion dollar industry. No more getting lost in the hood for you.
