early radio history
Radio broadcasting debuted in the early 20th century and grew rapidly through the 1930s-1950s, becoming a major source of entertainment and news. Technological advances in the late 19th century led to the development of radio. Guglielmo Marconi transmitted the first radio signal across the Atlantic in 1901. The first radio voice broadcast occurred in 1906. By the 1920s-1930s, radio stations proliferated and radio ownership expanded greatly. Networks emerged providing programming. Radio faced competition from television in the 1950s, but adapted through portable radios, new formats like top 40, and focusing on news and information.
