NT1 was created in 2004 by AB Groupe for the launch of the TNT platform scheduled for March 2005. In late 2004, AB Group announced their intention to call the channel La Quatre (The Four). However, in January 2005, France Télévisions announced that they would rebrand their channel Festival as France 4. AB Groupe decided to revert to the NT1 name.
On 24 July 2008, the channel announced it would broadcast the 2008–09A1 Grand Prix events on Sundays. This international racing series will be shown live or pre-recorded. The deal was confirmed by Richard Maroko, General Programmes Manager of the AB Group and Richard Dorfman, A1GP’s director of broadcasting.
