When Irishman John Boland travelled to Athens for the first modern Olympic Games in 1896, he had no idea he would return home with the gold medal in tennis. But then, he had no idea he would compete either - he went as a spectator.
Times have changed dramatically for Olympic tennis since then. Today's Olympic tennis players include some of the highest-profile athletes in the world.
Today, Olympic competition includes men's and women's singles and men's and women's doubles.
