Before Text Messaging They Had
Keeping in touch through Western Union was the only way to get in touch with someone quickly. These telegrams were sent across the world during the 1940's.
Telegrams sent by individuals, generally on the Western Union system, were charged for by the word and so tended to be used only for the most urgent communications.
Teletype machines were largely mechanical devices that automated telegraphy. A machine like a typewriter was used to input the communication and on the receiving end it was typically printed out on a paper tape. They were used by newspapers to receive breaking news.time-sensitive communications such as sports and stock-market reports.
