An overlook on the term "Broadcasting"

Broadcasting is the distribution of audio and video content to a dispersed audience via any audio or visual mass communications medium, but usually one using electromagnetic radiations. The receiving parties may include the general public or a relatively large subset thereof.

Broadcasting has been used for purposes of private recreation, non-commercial exchange of messages, experimentation, self-training, and emergency communication such as amateur radio and amateur television (ATV) in addition to commercial purposes like popular radio or TV stations with advertisements.
