Features: Radio and television are sometimes collectively referred to as "broadcasting." This means the term "broadcasting" has both broad and narrow definitions. Broadly speaking, broadcasting refers to the medium for transmitting sound programs or the dissemination of programs containing both images and sound through radio waves or wires. By transmission method, it is divided into wireless broadcasting and wired broadcasting; by the type of symbols transmitted, it is divided into sound broadcasting that transmits only sound, as well as television broadcasting that transmits both images and sound. After the advent of communication satellites, it was further divided into terrestrial broadcasting and satellite broadcasting based on whether it passes through satellites. Narrowly speaking, broadcasting refers to the transmission of only sound, while television broadcasting that transmits both images and sound is called television. China's radio and television industry has gone through decades of ups and downs, and with the country's prosperity and advancements in science and technology, it has developed into a nationwide radio and television broadcasting network. Radio and television have deeply penetrated society and households. External broadcasting has also been developing steadily, becoming one of the more influential media in the world.
