Cable News Network (CNN) begins broadcasting.

Cable News Network (CNN) is an American multinational news media company and the flagship property of CNN Worldwide, a division of Warner Bros. Discovery (WBD). Founded on June 1, 1980 by American media proprietor Ted Turner and Reese Schonfeld as a 24-hour cable news channel and headquartered in Atlanta, Georgia, CNN is the first television channel to provide 24-hour news coverage and the first all-news television channel in the United States.

Broadcasting is the distribution of audio and audiovisual content to dispersed audiences via an electronic mass communications medium, typically using the electromagnetic spectrum, in a one-to-many model. Broadcasting began with AM radio, which became popular around 1920 with the spread of vacuum tube radio transmitters and receivers. Before this, most implementations of electronic communication were one-to-one, with the message intended for a single recipient. The term broadcasting evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as early as 1898.
