Post, Telephone and Telegraph administration
PTT
<communications, company> (PTT) One of the many national
bodies responsible for providing communications services in a
particular country. Traditionally, PTTs had monopolies in
their respective countries. This monopoly was first broken in
the USA, with the UK joining somewhat later. Currently the
markets are being deregulated in Europe as well as other parts
of the world.
Well-known PTTs include {MCI}, {AT&T}, and {British Telecom}.
Compare: {telco}.
