ARD maintains and operates a national television network, called "Das Erste" ("The First") to differentiate it from ZDF, a.k.a. "das Zweite" ("The Second"), which started 1963, as a separate public TV-broadcaster. The ARD network began broadcasting on 31 October 1954 under the name of "Deutsches Fernsehen" ("German Television"), becoming "Erstes Deutsches Fernsehen" ("First German Television") with a corporate redesign in 1984; it adopted its current short name ("Das Erste") in 1994. ARD's programmes are aired over its own terrestrial television network, as well as on pay television.
