The early stages of fiction audio storytelling did not entirely resemble what would later be called radio documentary . In the 1930s , with radio stations like WNYC entering the airspace , reporters documented real people and real life scenarios through short on-the-ground interviews rather than dramatization . Other notable documentary broadcasts include the unrefined one-shot audio recordings of events , such as the Hindenburg disaster in 1937 . By 1939 , CBS responded to growing anxieties about immigration in the U.S. with a six-month series , titled " Americans All … Immigrants All , " that highlighted the stories of immigrant communities
