Broadcasting is the distribution of audio and video content to a dispersed audience via any audio or visual mass communications medium. The receiving parties may include the general public or a relatively large subset thereof. TV programs, radio programs, commercials in malls, the radio in school or train station, all agree with the definition of broadcasting. The term “broadcasting” in Chinese, refers more to the radio, while in Japanese and Korean, they adopt the Chinese phrase “放送”, meaning distribution, to refer to the same activity. The similar usage is also found in Taiwanese.
