or programmer to a prospective employer, and an archival record of content broadcast over-the-air made for legal archiving purposes. With evolving technology, the term came to be applied in the television industry as well.
A ''scoped'' (short for "telescoped"—by analogy with pressing the ends of a hand-held telescope to reduce its size) aircheck usually contains only segments where the announcer is actually talking, along with a bit of the music or commercial on either side. In an ''unscoped'' aircheck, all programming is left intact and unedited, including music, commercials, newscasts, jingles and other on-air events.
The term is also applied by some to recordings made "off-the-air" by listeners, using consumer or semi-professional equipment. These airchecks became more common with the advent of commercial
cassette recorders.

, which apparently wanted to monitor the then-rising young singer. The sound of the recording suggests that it was made by placing an open microphone before a high-quality radio (a method known in the radio trade as a "mic-feed").

Some radio stations used "logger reels" for airchecks. On these large reels of tape would be recorded the air signal at super-slow speeds. These reels were kept by the station for regulatory purposes (e.g. to provide an audio record that commercials ran as logged or to confirm aired content after allegations of inappropriate content). After a time, normally around 30 days for most stations, these logger reels would be reused or discarded.
Many airchecks are made by the announcers themselves on a recorder that begins recording when the microphone is turned on and then goes into pause when the microphone goes off. In the 1960s and 1970s reels of tape were used for these "skimmer" airchecks. Later it was cassettes. Today most stations use computer

Uses
DJs use airchecks to critique themselves, sometimes with the Program Director listening along with them to provide suggestions for improvements. Announcers keep some of their airchecks as "audio snapshots" of their career.
Airchecks are also recorded at radio stations to send to clients to demonstrate how their live commercials, remote breaks or contests sounded.
Some airchecks of older radio programs are highly prized by collectors, due to their

, and a surprising number have survived. Another class of aircheck has to do with transitions between programming
formats on a given station, where recordings are made of the final hours of an old format or early beginnings of a new format.
A large number of airchecks have survived from listeners during the Top 40 era, many of whom recorded talented DJs to learn how to be DJs, and many who recorded Top 40 music because it was cheaper than buying the 45s. Still others were, and still are, recorded by radio personalities themselves for archiving their own work. Many have been donated to online aircheck "museums", such as
