History

"Going dark" was initially coined after a term used to describe a broadcast tower whose aircraft warning light system had failed, leaving the tower dark at night, and leaving pilots vulnerable to possibly striking it when flying through darkness.

Transmitter operations

According to the FCC, a radio or television station is considered to have gone dark or silent if it is to be off the air for 30 days or longer. Prior to the Telecommunications Act of 1996

, a licensee is no longer required to surrender the license while dark. Instead, the licensee may apply for a "Notification of Suspension of Operations/Request for Silent STA" (FCC Form 0386), stating the reason why the station has gone silent.

A service can go dark for any number of reasons, including, but not limited to, financial resources being drained to continue effective operation of the service as being of benefit

In economics, a public good is a good that is non-rival and non-excludable. Non-rivalry means that consumption of the good by one individual does not reduce availability of the good for consumption by others; and non-excludability means that no one can be effectively excluded from using the good...

 that has rendered the facility inoperable; or technical adjustments that would make it prohibitively expensive to perform the work and carry on the normal operations of the station in question.

The service is not required to notify the FCC of silence if the period of silence is less than 10 days. If the period of silence is to last at least 10 days but less than 30 days, the licensee must notify the FCC in writing explaining why the service is silent and an expected return to the air. A service that expects to be silent for more than 30 days must apply to the FCC using Form 0386, which can be done electronically (preferred method) or by a paper application. On this application, the date the station has gone dark or its targeted date to go silent must be stated on the application, along with the reason for silence. The Silent STA (special temporary authority

The station is required to provide the FAA with its assigned tower number, latitude and longitude coordinates, and an anticipated time that the tower light operations will resume. A licensee has 15 days to make the necessary repairs until the FCC is notified by the FAA. Once repairs are made, the FAA must be notified that all is well.

s of many small-town broadcasters with small audiences and revenues. Under the Telecommunications Act of 1996, licensees of stations that were listed as "silent" by the FCC (at the time around 400) were warned to either power their facilities back up or their licenses would be canceled permanently. The FCC did allow reasonable provision for broadcasters who notified them that they were trying to get back on the air. Nevertheless, many licenses were canceled, primarily those with abandoned facilities.
