ARD ONE
One is a German free-to-air television channel owned and operated by the German public-broadcasting consortium ARD. Managed since October 2005 by Westdeutscher Rundfunk on behalf of ARD as a whole, the channel was originally launched (as EinsFestival) on 30 August 1997.
From 21 to 24 March 2008 Einsfestival ran HDTV test broadcasts via satellite and digital cable (exclusively on Kabel BW). The first HD transmissiones came from the Internationale Funkausstellung Berlin. Between 22 December 2008 and 1 January 2009 Einsfestival again aired HD test shows.
