The BBL has been the pinnacle of men's basketball in Britain, since its initiation in 1987.
The WBBL was founded more recently in 2014, in an attempt to create a high-quality professional league for women.
The Leicester Riders are the current holders of the men's league, while Nottingham Wildcats romped to victory in the women's competition last season.
Basketball originated, developed and flourished in the United States - but the British game is enjoying a recent surge in attendances at venues across the country.
The BBC are set to broadcast 32 live British Basketball League (BBL) matches this season, including eight games from the British Basketball Women's League (WBBL).
This evening, we will have live coverage on the BBC Sport website of the BBL tie between Glasgow Rocks and London Lions at the Copper Box Arena.
