In 1922, the Deutsche Stunde, Gesellschaft für drahtlose Belehrung und Unterhaltung mbH (German Society for Wireless Instruction and Entertainment Limited) was formed to promote the new science of radio broadcasting and reception.
Similarly, the United States created Rundfunk im amerikanischen Sektor (RIAS) for their zone in Berlin.
In June and July 1953, a strike by construction workers in the German Democratic Republic (GDR) led to an uprising of the people of the communist state which was violently put down by Soviet forces and the Volkspolizei.
The new Sender Freies Berlin began broadcasting two services, SFB1 and SFB2 on 1 June 1954, and joined the ARD in September 1954.
The GDR's national television service was closed and replaced by four ARD regions: an expanded NDR in the north; the continuing SFB in Berlin; and the new Mitteldeutscher Rundfunk (MDR) in the south and Ostdeutscher Rundfunk Brandenburg (ORB – East German Broadcasting – Brandenburg) in the east.
On 22 February 1993, the SFB began a joint venture with the new ORB to create Radio BZWEI, a news and information service for the east of the country aimed at 25 to 50-year-old listeners.
In 1995 the Ostdeutscher Rundfunk Brandenburg in coalition with the Sender Freies Berlin started their Internet radio streaming service Info-Radio on Demand.
On 3 October 1997, SFB and ORB launched RADIOkultur, a cultural station taking up much of the programming of SFB3, with an emphasis on classic, world, jazz and new music and politics.
