High Quality Content by WIKIPEDIA articles! An Off-Air Pickup was a method used by some small market television stations in the United States to receive and relay network programming. In the 1950s, a network of AT&T coaxial cable and microwave relays known as Long Lines was constructed. These circuits could be (and were) used for normal telephone traffic, but were also utilized to relay the video signals of the three U.S. commercial television networks (ABC, CBS, and NBC) to their various affiliated stations around the country. This enabled those affiliates to all carry network programming "live" at the same time. There were, however, a handful of small-market TV stations that were not able to be connected via Long Lines due to their remote geographic location. In some cases, network shows were recorded (either as a kinescope or, starting in the late 1950s and early 1960s, on videotape) and sent to the station via mail or courier, to be aired on a delayed basis (usually a one-week delay).
