In the original incarnation, telegraph was an "express mail service", where you took your (short) letter down to the railway station[*]; the telegraph operator sent the message in morse code down the line, until it wound up in the destination city, where it would get transcribed on paper and be delivered by messenger. In order to deliver the message, it needed to contain the destination street address. Since the messages were charged by the word, this could be quite a significant fraction of the cost, as well as being cumbersome and error prone. Thus began the practice of registering one-word "cable addresses", such as "Tribune, Chicago". I.e. the address would be just one word besides the destination city name. Since this produced less revenue for the cable carrier, they charged for registering the address. When TELEX was introduced, it was first used as an update to the implementation of the telegraph system. TTYs operated on point-to-point lines, and operators carried punched tapes across the room for the next hop of the journey of the message. This was faster than morse code, and required less operator training. Later, automated circuit switches (imported from the telephone world) allowed end-to-end connections, for the duration of the message, and allowed the wire carriers to lease terminals to subscribers for installation on their premises, similar to telephones. This must have happened in the 1940's or thereabouts. While the storefront small-user service remained unchanged, it was at that point merely an emulation of the old user interface; the whole system ran internally on dial-up TELEX service. When I lived in Denmark until ten years ago, the post office still offered telegram service, complete with messenger delivery. You could also phone in telegraph messages, and they would be charged on your phone bill, in the same manner as operator-assisted long-distance telephone calls. There was a SEPARATE service offered by the phone company, called "phono-telex" which was cheaper, for submitting messages to telex subscribers; i.e. there was no messenger involved. By the 1970's, old fashioned telegrams were only used for formal greetings to formal parties, such as weddings, confirmations, anniversaries, cityhood anniversaries, ship launchings, party congresses etc. For such occasions, the Postal Service offered formal "celebration forms" with art prints in various styles. I recently heard that the old fashioned telegraph service has now been completely abandoned, but at the same time souvenir covers are now offered as a delivery option for special delivery fax messages. The more things change, the more we get to appreciate the funny ways in which history survives. [*] The railways needed telegraphs for co-ordinating operations; it was natural that they should try to make a business out of excess capacity. But as the telegraph business grew, it apparently was spun off. I often wonder if the "Western Union" company is not really a railway company that has stopped running trains. Pat, do you have a piece on the history of WU ? / Lars Poulsen, SMTS Software Engineer CMC Rockwell lars@CMC.COM [Moderator's Note: There were numerous small telegraph companies all over the United States in the 1860-80 period. A group of investors began buying them up, using a lot of the same tricks -- uh, excuse me, I mean 'business techniques' -- Ted Vail would use a half century later to grab up hundreds of tiny telcos everywhere for his 'one way of doing things' Bell Telephone System. It was this merger, or 'union' of many telegraph companies, all of whom would be sharing their lines and facilities which led to the organization we call Western Union Telegraph Co. The fact that there were few competitors left in the United States attested to their success in monopolizing the market. Just as Ted Vail and his pals began an agressive effort to grab as much as possible once the patents on the telephone expired -- which forced them to deal with competitors -- so Samuel Morse and his partners wasted no time once Mr. Morse's patent was due to expire. By the time the telephone was invented, Western Union was already a huge organization. Unlike Alex Bell's first message on the telephone, ("Watson! Come here, I want you."), the first telegraph message from Samuel Morse to an associate was "What Hath God Wrought?" Indeed. PAT]
