Station identification

Station identification (ident, network ID or channel ID) is the practice of radio or television stations or networks identifying themselves on-air, typically by means of a call sign or brand name (sometimes known, particularly in the United States, as a ""sounder"" or ""stinger"", more generally as a station or network ID). This may be to satisfy requirements of licensing authorities, a form of branding or a combination of both. As such, it is closely related to production logos used in television and cinema, alike.Station identification used to be done regularly by an announcer at the halfway point during the presentation of a television program, or in between programs.
