Broadcasting in mass communication refers to the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and receivers. Broadcasting can be done through various mediums such as television, radio, newspapers, magazines, and digital media including the Internet, emails, and texts. The field of broadcasting includes both government-managed services such as public radio, community radio, and public television, and private commercial radio and commercial television. The U.S. Code of Federal Regulations, title 47, part 97 defines "broadcasting" as "transmissions intended for reception by the general public, either direct or relayed". Broadcasting is a way to deliver messaging over networks that expose mass audiences to cultural, artistic, or political shifts and discussions in society. The value that broadcast media provides is in the information it communicates, which informs and educates the public. It can include public service announcements (PSAs), daily news, weather forecasts, interviews, and documentaries. It can also be recreational, including things such as reality television (TV), films, sports, advertising, and comedy.
