It was exactly a hundred years ago, on 18 May 1923, that listeners in Czechoslovakia were first able to tune in to regular radio broadcasts. Much has changed since then. Today Czech Radio has ten nationwide stations and fourteen regional studios, based in towns and cities around the country. And of course, there is also Radio Prague International, broadcasting in seven languages around the world. Back in 1923 there was just one station, which in those early days broadcast for a few hours every day from a scouts’ tent on the edge of Prague. To mark the anniversary, we take a journey through the radio archives.
