The Toddlers' Truce policy may have originated when the BBC resumed television after the end of World War II on 7 June 1946. The policy remained fairly uncontroversial until ITV began broadcasting on 22 September 1955: at that time, the Truce was accepted as policy by the Postmaster General, the Earl De La Warr interests of smoothing relations between ITV and the fledgling Independent Television Authority.
