Television and radio broadcasting involve the production and performance of news and entertainment programs.

Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications.

Prior to the 1920s, the radio was primarily used to contact ships that were out at sea. Radio communications were not very clear, so operators typically relied on the use of Morse code messages. This was of great benefit to vessels in the water, particularly during emergency situations.

The prime purpose of radio is to convey information from one place to another through the intervening media (i.e., air, space, nonconducting materials) without wires. Besides being used for transmitting sound and television signals, radio is used for the transmission of data in coded form.

Radio is sound communication by radio waves, usually through the transmission of music, news, and other types of programs from single broadcast stations to multitudes of individual listeners equipped with radio receivers.

Radio signaled a major shift in how Americans communicated. Once radios became widespread and affordable, they connected people in ways never before possible. By the 1920s, a few decades after Marconi's first broadcast, half of urban families owned a radio. More than six million stations had been built.
