History of Südwestrundfunk

In Bavaria and in Württemberg-Baden, Radio München (Munich) and Radio Stuttgart went on air in 1945. In the next years, Radio München was transformed to a Bavarian broadcaster, and in Germany's South West, two public broadcasting corporations started and produced radio and (subsequent) television programs up to their merger in 1998: Südwestfunk, SWF, in the former French zone, founded in 1946, and Süddeutscher Rundfunk, called "Südfunk", short SDR, founded in 1949.
