British Basketball has signed a 10-year deal with new broadcaster MKTV, which is due to launch early next year.
The agreement will see 40 BBL games live in prime-time on one of MKTV's channels on the Sky satellite platform.
"Increased coverage should dramatically raise the game's popularity and allow us to retain future stars in this country," said BBL chairman Paul Blake.
MKTV will also contribute £2.5m to fund BBL development posts and help the league to secure a main sponsor.
Jawad Siddiqui, chief executive of MKTV, said: "Basketball is one of Europe's fastest growing sports. Our collaboration with the BBL will create the exposure the sport's thriving grass-roots fan base deserves."
The BBL has lost three of its professional teams since last season, with Brighton, Birmingham and the London Towers all dropping out.
Two teams have joined the top flight - London United and Worcester Wolves.
The British game is under pressure to raise its standards and unearth new talent before the London Olympics in 2012.
The new BBL season gets under way on Friday, 29 September.
