, introduced a tape delay system consisting of an external playback head, which was spaced far enough away from the record head to allow for a five-second delay. A system of rollers guided the tape over the playback head before it wound up on the take up reel. This system was introduced in 1952 when WKAP started a talk show called "Open Mic". It is believed that this was the first time a telephone call-in show was broadcast with the telephone conversation "live" on the air. The FCC rules at the time prohibited the broadcasting of a live phone conversation. However, there was no rule prohibiting a taped playback of a phone call, provided that a "beep" tone was heard by the caller every 15 seconds so that the caller knew he was being recorded. The five-second delay constituted a "taped" phone conversation, thus complying with FCC regulations, that being a legal fiction

The broadcast profanity delay was invented by C. Frank Cordaro (July 13, 1919 - February 20, 1997) who was Chief Engineer of WKAP, originally on AM 1320, in Allentown, Pennsylvania during the 1950s and early 1960s. Ogden Davies, then General Manager of WKAP, assigned Cordaro the task to develop a device whereby profanity during a "live" conversation could be deleted by the radio talk show host before it was broadcast. This new device was to be used on the "Open Mic" radio talk show. The device Cordaro developed was the first tape delay system. WKAP was one of several stations owned by the Rahal brothers of West Virginia (later Rahal Communications). First tested and used at WKAP, this tape system for broadcast profanity delay was then installed at the other Rahal-owned radio stations. From the Rahal brothers stations, the broadcast profanity delay went into common usage throughout the US.

. created the first digital broadcast delay for this purpose. The device (known colloquially as a "dump box") had a large "DUMP"/"DELAY DUMP" button that would bring the delay to zero, thus removing unwanted segments. In addition to this convenience, it would also "rebuild" the delay time by unnoticeably lengthening the normal pauses in spoken material. Thus, a minute or so later, the broadcaster would again have full delay, often leaving the listener unaware that material had been deleted.

In modern systems, a profanity delay can be a software module manually operated by a broadcast technician that puts a short delay (usually between five and ten seconds) into the broadcast of live content. This gives the broadcaster time to censor

 the audio (and video) feed. This can be accomplished by cutting directly to a non-delayed feed, essentially jumping past the undesired moment (something that can be quite jarring to a viewer or listener). In other cases, dedicated hardware units similar to the original digital unit but with improved quality and editing capability can be used. These products can even "build up" delay with difficult program material such as music. Alternatively, a bleep noise or other substitute sound
