On March 30, 2017, SpaceX launched the SES-10 communications satellite on a Falcon 9 whose first stage had flown before. That booster had launched a cargo mission to the International Space Station in April 2016 and then landed on a drone ship.
It was the first time an orbital-class rocket booster had been reflown. The booster landed on a drone ship once again after the flight.
SpaceX said reuse was the key to lower costs. Booster reflights became routine, and individual boosters have since flown many times.
