ETB 1 is the first television channel from the Euskal Irrati Telebista group in the Basque Autonomous Community, Navarre, and the French Basque Country. The channel broadcasts entirely in Basque.
The channel began test transmissions on 31 December 1982 and officially launched on 16 February 1983 as ETB, using this name until the launch of its sister ETB 2 on 31 May 1986. ETB was renamed as ETB 1 at that moment. An HD feed of ETB 1 was launched on 21 December 2016.
Its reception area comprises the whole Basque Country — i.e. the Basque Autonomous Community, Navarre and the Northern Basque Country — and some surrounding places.
Its programming includes interviews, films, documentaries, sports, youth and children's programmes, making a strong emphasis on sports and children's programming.
The EiTB group's second main television channel, ETB 2, broadcasts in Spanish.
