1938 in radio

Events

• 3 January – The BBC Empire Service, begun in 1932, transmits its first programme in a foreign language: Arabic.
• 13 March – CBS carries the first point-to-point news roundup, including Edward R. Murrow's first live report, as part of its coverage of the Anschluss in Austria. Over the next few months, the daily programme will evolve into the CBS World News Roundup, a permanent fixture on the CBS network.
• 15 March – The BBC begins its Portuguese and Spanish service for Latin America.
• 14 April – Fireside chat by the President of the United States: On Economic Conditions.
• 6 May – The Caferadio copyright case is decided by the High Court of the Netherlands in favour of the composer Franz Lehár, who complains about a cafe owner allowing his customers to listen to a radio broadcast of Der Zarewitsch.
• 24 June – Fireside chat: On Party Primaries.
• 11 July – The first live drama adaptation in Orson Welles' The Mercury Theatre on the Air series on CBS Radio in the United States is broadcast: Bram Stoker's Dracula.
• 12 September – Commentator H. V. Kaltenborn begins his famous marathon of news bulletins on the CBS network in the United States covering the intensifying Czech Crisis over the Sudetenland. The first bulletin is a summation of Hitler's closing address to the Tenth Party Congress of the Nazi party in Nuremberg.

• 30 October – Orson Welles's radio adaptation of The War of the Worlds is broadcast on CBS from New York as an episode of The Mercury Theatre on the Air.

This approach results in panic in various parts of the United States, although later research suggests its level has been exaggerated.
