telex

Imagine a time before email and before fax became common. That's where the telex came in. It was a system for sending written messages electronically over communication lines, using teleprinters that typed the message out at the other end. Think of it as an early form of long-distance text messaging for business and government. For decades, people used it to send orders, contracts, shipping details, and other urgent information. The word can mean the network itself, a message sent that way, or the act of sending one. It is largely obsolete now, replaced by fax, email, and other faster tools, but you may still see phrases like "sent via telex" in older documents, books, or films.

The word telex is short for "teleprinter exchange." It refers to an international text communication system that used teleprinters, and it can also refer to a message sent through that system or, as a verb, the act of sending such a message. A person would type a message into a teleprinter, and the machine would send it as electrical signals over a network to another teleprinter, where the text would be printed on paper. It was not voice communication like a phone call; it was purely text-based.

Telex machines were standardized internationally, so messages could be sent between offices in different countries with relative ease. That made the system very useful for international business, shipping, news work, and diplomacy during its peak years. Unlike telegrams, which usually depended on operators and Morse code systems, telex let ordinary office workers type and send messages directly. It was slower than speaking on the phone, but it created a clear written record, which was often important.

The system began to decline when fax machines became more common in the 1980s, and email later made it almost entirely obsolete. Today, you are most likely to encounter telex in historical writing, period films, business records, or legal and shipping documents from earlier decades. Sometimes the word points to the old machine or network, and sometimes it simply means "a typed electronic message sent by that system." In modern use, it often carries a strong sense of the past and may even be used to stress how outdated a method or idea feels.
