A telegram sent for christmas, in 1951
A telegram (Greek tele: distant and gramma: letter) is a written message transmitted by using an electric device. The message was carried along wires, and the text written or printed and delivered by hand or teleprinter.
Telegrams were very widely used, but are now not useful because most people use telephones and e-mail. The idea was developed by the BritishPost Office as a service for urgent letters.
