Broadcasting

Broadcasting is the distribution of audio and video signals (programs) to a number of recipients ("listeners" or "viewers") that belong to a large group. This group may be the public in general, or a relatively large audience within the public. Thus, an Internet channel may distribute text or music worldwide, while a public address system in (for example) a workplace may broadcast very limited ad hoc soundbites to a small population within its range. The sequencing of content in a broadcast is called a schedule. Television and radio programs are distributed through radio broadcasting or cable, often simultaneously. By coding signals and having decoding equipment in homes, the latter also enables subscription-based channels and pay-per-view services. A broadcasting organization may broadcast several programs at the same time, through several channels (frequencies), for example BBC One and Two. On the other hand, two or more organizations may share a channel and each use it during a fixed part of the day. Digital radio and digital television may also transmit multiplexed programming, with several channels compressed into one ensemble. When broadcasting is done via the Internet the term webcasting is often used. Broadcasting forms a very large segment of the mass media. Broadcasting to a very narrow range of audience is called narrowcasting.
