The new BT Sport service goes live tonight (Thursday August 1st) at 6pm, with a special launch show on BT Sport 1 and BT Sport 2.
BT Sport will introduce its new presenting team - which features the likes of Jake Humphrey, Clare Balding and Craig Doyle - with a live broadcast from its new, purpose-built studio in Queen Elizabeth Olympic Park.
The majority of UK viewers will be able to enjoy the BT Sport launch night - regardless of whether they have signed up for the new service or not.
This is because, for one night only, BT Sport is free-to-air on Freeview channel 57 and Sky Guide channel 413.
Viewers will be able to enjoy a host of sports-related content on BT Sport 1, BT Sport 2 and ESPN in the coming weeks and months - including live football, rugby union and women's tennis, plus UFC and Moto GP.
The jewel in the BT Sport crown is 38 live Premier League football matches per season, including 18 of the top-pick games.
BT Sport will also broadcast live Aviva Premiership rugby union, and more than 800 hours' per year from the WTA tennis tour.
