Mediator was the civilian part of the ATC system for Area Control in theU.K. (except Scottish FIR) which came into being in the late 1960's early 1970's. The military function was known as Linesman. The full title was unsurprisingly LInesman Mediator. The Linesman part fell out of usage and "the Thing" became known as Mediator, which has now sadly passed on.
