Bulgarian radio drama first appeared in 1945, broadcasting live from the national studios. The immediate postwar years were difficult throughout the country, both in economic and political terms. The socialist revolution and takeover, on 9 September 1944, soon imposed strict criteria on dramatic creation and artistic achievement, presumably on world standards. Radio drama, as one of the key instruments in the new national, revolutionary symphony, could not but play in general harmony. It naturally developed according to patterns governed by the political authorities. It contributed to programmes devoted to promote conflict, action, heroes, virtues abounding in the young socialist doctrine. Russian plays and novels were selected and broadcast as master keys in the opening of popular minds to the new philosophy. Broadcasting slots allowed some room for the production of the emerging Bulgarian literature of the late nineteenth century. Plays and playwrights from other parts of the world remained ignored by those in power and, as a consequence, by the production teams and the general audience.
