Nowadays, many networks have complete sets of idents based on a central theme or branding element, and most of the time these idents also build the basis for the rest of the appearance of the channel. Television idents have evolved, from mainly being mechanical models such as the famous BBC Globe, and the advancements of computer technology allowed television presentation to enter the modern era throughout the 1980s and 1990s.

At one time, the FCC gave specific guidelines for how close to the top of the hour stations were expected to be:

  • "as close as possible" for programming that had no definite break on the hour, such as speeches and classical music

 has made it much easier for broadcasters to ensure compliance with identification rules. Many television stations and some radio stations have their identifications programmed to play automatically at the appropriate times.

Why identification is required


Station identification is used because of the sheer number of signals available over the air. Not only are there radio and television signals being broadcast, there are also two-way radio signals from police, emergency crews and private companies as well as amateur radio
Amateur radio

 signals. Early radio operators recognized the need for anyone listening to a signal over the air to be able to tune in a specific time and immediately know what station was being heard and where the signal was originating from.

Additionally, from the FCC's perspective it is critical to be able to positively identify the source of a broadcast that is not complying with federal regulations.

According to United States law, the FCC can fine or reprimand a station for failing to make the appropriate identification.

Identification on other types of signals


In the United States, the policy on radio identification depends on the service. Station identification is usually done in the station's standard mode of operation, though the FCC considers Morse code identification to be universally acceptable no matter what mode the station is operating in.

Radio identification

Radio stations are required to verbally identify themselves each hour. The station must announce its legal call sign

, community of license, and any other call signs it uses. Some stations broadcast on more than one frequency and are required to announce these as well. However, stations do not have to announce all translators each hour. Most stations announce only a few each hour on a rotating basis. Some stations make it a practice to announce all main call signs as well as all translators at a certain time of the day, such as midnight. Some radio stations also announce the signal strength of each translator. Some radio and television stations will also use a larger nearby city they serve that is not the city of license
City of license

A city of license or community of license, in United States and Canada broadcasting, is the community that a radio station or television station is officially licensed to serve by that country's broadcast regulator....
. (example: "WSNE

") This is acceptable as long as the first city mentioned immediately after the call sign is the station's city of license. Although it is not required, some radio stations will also announce their frequency or dial setting during the station identification.

Some stations downplay their actual city of license and favor the major city it's associated with instead. For example, "WKTU

", where "Lake Success" is said very quickly and with less inflection before the much more prominent "New York". Some stations choose to run their legal ID sandwiched between two commercials in a stop set (commercial break) that is close to the top of the hour.

Proper format
Radio announcers must be careful to announce the station identification exactly as instructed by the FCC. For example, if station doesn't have the "FM" part on its official license and registration with the FCC, the announcer cannot say it. In addition, announcers need to be careful to avoid adding additional words between the call signs and the community names, and are disallowed from making the station identification in the form of a complete sentence. For example, saying "This is W/K--based in Anytown" is not acceptable because of the words "based in." The community name should immediately follow the call signs, according to FCC regulations. The format is: WXXX/KXXX, City of License. Anything else is not a legal ID.

There are, however, some more creative ways of announcing station identification that are legal. For instance, KRPN (now KMRI

 N Salt Lake City. Because the call sign KRPN (with the "N" serving as a homophone for the word "in") and the city of license are stated in the proper format, it is a legal identification, despite the extra W in front.

Many radio stations post a sign in their studios with the official and correct identification announcement printed on it so announcers are always reminded of the correct, legal identification. Most have a prerecorded station identification, which reduces errors.

Low-power (Part 15 in the U.S.) stations do not always identify, being unlicensed (this would be essentially impossible for small FM transmitters for consumer use, such as those used to broadcast music from an MP3 player to a car radio), but those that run as community-based radio stations (including college stations using carrier current

) usually do. Station identification in that case usually consists of the station's name, frequency, and a slogan; unlicensed stations are not allowed to use formal callsigns.

Shortwave radio operates in the frequency range of 3,000 kHz to 30,000 kHz . In radio, short wavelength corresponds to high frequency given the inverse relationship between frequency and wavelength, thus, ?shortwave radio? is denominated so, because its wavelengths are shorter than the long wave-lengths used in early radio communications; m...
 broadcasters usually do not use callsigns, instead giving the name of the service and the location of the home office, and occasionally the frequencies that the current broadcast is being transmitted on. There are a few exceptions, particularly in the United States, the time station WWV being a prime example.

With the advent of digital radio, station identification becomes more complicated, because more than one audio stream can be part of the same station. The FCC clarified what is required in these cases in :
§ 73.1201 Station Identification. (b) Content. (1) Official station identification shall consist of the station's call letters immediately followed by the community or communities specified in its license as the station's location; Provided, That the name of the licensee, the station's frequency, the station's channel number, as stated on the station's license, and/or the station's network affiliation may be inserted between the call letters and station location. DTV stations, or DAB Stations, choosing to include the station's channel number in the station identification must use the station's major channel number and may distinguish multicast program streams. For example, a DTV station with major channel number 26 may use 26.1 to identify an HDTV program service and 26.2 to identify an SDTV program service. A radio station operating in DAB hybrid mode or extended hybrid mode shall identify its digital signal, including any free multicast audio programming streams,in a manner that appropriately alerts its audience to the fact that it is listening to a digital audio broadcast. No other insertion between the station's call letters and the community or communities specified in its license is permissible.


Television identification

As noted above, 47 CFR 73.1201 mandates that television stations are also required to identify themselves each hour. However, because television is a visual medium, these announcements can be either visual or audio. Again, the station must identify its main callsign along with the community of license and any other call signs it uses. Television stations must also include their FCC-assigned on-air channel number. Translators are not required to be announced, though many stations make it a practice to display a list of all translators at a particular time of the day.

Combining identification with promotion
Wtkrpromotionid
Many television stations have devised a clever way to use station identifications as a promotional tool. By combining a short promotion for an upcoming show the station can fulfill its identification requirements while building its audience. For example, a station may show video of a local fire and tell them to tune in to the next newscast. During this short clip, the station will run its call signs and communities on screen, often in very small type. No audio announcement of call signs is necessary if the information appears on screen, so stations are free to use, in this example, the audio of an anchor or reporter promoting the story. Stations also use similar techniques to promote entertainment shows. If the correct and complete information appears on screen, it is a legal identification.

Any combination of this is also acceptable. For example some stations air a short (5 to 10 second) announcement with their station logo and an announcer reading their call signs. In this example the communities the station serves were not announced verbally.

As an example, in the 1990s, radio station WQLR

) at the top of the hour. The weather report would be prefixed with "WQLR Kalamazoo Accuweather", and because the callsign and city are announced back-to-back, it is a perfectly legal station identification.
