The prize fund for the Davis Cup currently is €23 million. It is not just the players that take home some of the prize money though. The federations of each country that oversee the sport will benefit from how well their team performs.
The first tournament
Davis was one of the players in the first tournament and his team won their first three matches. In the years that followed the tournament expanded to include other countries, including Belgium, Austria and France. It was in 1972 that it became a knockout tournament. The organizers created a tiered system of competition in 1981 and since then there have been regular revisions to the format.
