Broadcast delay

As a result, until today, many live programs, such as music and talent competition shows, are usually tape delayed for the western half of the country and aired as-live (although they may include edits to streamline the broadcast or resolve technical faults).

The continents of Europe and Africa, which both fall in the same range of time zones, are receptive to each other's live telecasts, while most of Asia from India eastwards, which includes China alongside the most populous time zone in the world, also receive simultaneous live telecasts within those cluster of regions.

In addition, television networks nowadays mandate prime time rebroadcasts (featuring edits as desired by broadcasters) for regions that are not covered by the original live primetime broadcasting and previously and solely relied on delayed telecasts on prime time among these otherwise live events.

The broadcast profanity delay was invented by C. Frank Cordaro (July 13, 1919 – February 20, 1997), who was Chief Engineer of WKAP during the 1950s and early 1960s.

Ogden Davies, then-General Manager of WKAP, assigned Cordaro the task of developing a device whereby profanity during a "live" conversation could be deleted by the radio talk show host before it was broadcast.

First tested and used at WKAP, this tape system for broadcast profanity delay was then installed at the other Rahal-owned radio stations.

[citation needed] John Nebel, who began a pioneering radio talk show in New York City in 1954, was one of the early users of a tape delay system that was invented by his engineer, Russell Tinklepaugh.

In 1977, the capacity of RAM (random-access memory) had reached 16 kilobits per chip, enough to think about using computerized digital audio means to create a sufficient delay for content deletion.

In addition to this convenience, it would also "rebuild" the delay time by unnoticeably lengthening the normal pauses in spoken material.

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).
