BBC Sport will broadcast the ATP World Tour Finals until 2018 after extending its deal to cover the season finale.
The event sees the eight best qualified men's singles players compete on hard court at London's O2 Arena.
This season's tournament begins 13 November and new world number one Andy Murray meets Marin Cilic a day later.
Barbara Slater, BBC director of sport, said the deal "shows our longstanding commitment to ensuring top class tennis reaches the widest possible audience".
She added: "The ATP World Tour Finals remains one of the standout moments in the sporting calendar bringing together the best players in the world to create a truly unique atmosphere.
