McDonald's will roll out self-order kiosks to 1,000 stores every quarter for the next two years, according to CEO Steve Easterbrook.

The kiosks were already in roughly 3,500 US McDonald's restaurants as of March, or about one-fourth of its domestic stores. They will be in about half of US restaurants by the end of 2018 and in all stores by 2020. McDonald's locations in Australia, Canada, and the UK are even further along in kiosk usage.
