Radio network
A
radio network is a network system which distributes
programming to multiple
stations simultaneously, or slightly delayed, for the purpose of extending total coverage beyond the limits of a single broadcast signal. The resulting expanded audience for programming essentially applies the benefits of
mass-production to the
broadcasting enterprise.
Most radio networks also produce much of their programming. Originally, radio networks owned some or all of the radio stations that broadcast the network's programming. Presently however, there are many networks that do not own any stations and only produce and/or distribute programing. Similarly station ownership does not always indicate network affiliation. A company might own stations in several different markets and purchase programing from a variety of networks.
Radio networks rose rapidly with the growth of regular broadcasting of radio to home listeners in the
1920s. This growth took various paths in different places. In
Britain the
BBC was developed with government funding and a broadcasting monopoly in its early decades. In contrast, in the
United States of America various competing commercial networks arose funded by advertising revenue. In that instance, the same corporation that owned or operated the network often manufactured and marketed the listener's radio.
Major technical challenges to be overcome when distributing programs over long distances are maintaining signal quality and managing the number of switching/relay points in the signal chain. Early on, programs were sent to remote stations (either owned or affiliated) by various methods, including leased
telephone lines, on pre-recorded
gramophone records or audio tape, and somewhat later via microwave relay stations. Later on
coaxial cable linking stations became the norm, as it provided the best cost-benefit ratio.
Many early radio networks evolved into
Television networks.
