It was launched on February 6, 2014 as "BNT HD" with the start of the Sochi 2014 Olympic Games.

Beforehand, BNT used to air sports events such as the 2010 FIFA World Cup and the London 2012 Olympics in HD on temporary HD channels which used to upscale the BNT 1 channel.

In 2014, the national television decided to launch BNT HD as a fully scheduled channel.

Some of the shows aired include The World Sailing Show, Monster Jam (автомобилно шоу), Extreme E - Electric Odyssey, and One Water Race.
