instance, when a speech by Winston Churchill was jammed. Pearson added that the Army had located the sources of the interfering transmissions and "proposes to retaliate if this deliberate interference isn't stopped." By September 1944, however, William S. Paley, chief of radio for the Supreme Allied Headquarters in Europe, announced, "The Allies have won the battle of the airwaves hands down." Although Paley's comments focused on attempts to jam shortwave broadcasts to troops, the article noted that jamming of transmissions for use in The Army Hour had been circumvented by using recorded material rather than live shortwave transmissions. Censorship Miller wrote, "A program that is as close to the armed forces as is 'The Army Hour' stands in constant danger of revealing vital information." Despite that danger, the program's producers consistently managed to keep American listeners informed without "revealing vital information." Technology In 1943, NBC waived its own rule against using recordings in order to broadcast details of a battle in Sicily and what soldiers involved felt and said. Army Signal Corps personnel recorded the material on sound films, which were edited and transferred to disc for use on The Army Hour. A new development in recording technology, wire recording, helped The Army Hour with both transmission of programs to soldiers and coverage of war activities. A 1943 newspaper story reported that a spool of wire "no larger than the ordinary doughnut" could record The Army Hour and two newscasts in the United States. The wire was then flown to Algiers for transmission to troops. The same technology eventually was used to record reports that were broadcast as part of The Army Hour. A story in Broadcasting magazine in 1945 told of one reporter's capturing the sounds of war from "the lead plane of the Allied airborne invasion of Germany" and another's preparing a report via wire recording of 10 hours of bombardment. Popularity and recognition By the time it had been on the air three months, The Army Hour had become the highest-rated Sunday daytime program as measured by Hooper Ratings. At that time, it was carried by 115 domestic radio stations and transmitted outside the United States by six shortwave stations. A trade publication reported on two ways in which the audience was supplemented: Some stations recorded The Army Hour broadcasts and played the recordings for re-broadcasts to accommodate additional listeners.
