1. The Telegraph
Yes, Virginia, you can still send a telegram, though not through Western Union. It sent its last telegraphic transmission on January 27, 2006. At the telegram's peak in 1929, more than 200 million were sent. By 2005, that number had dwindled to 21,000.
Subsequently, iTelegram took over Western Union's telex network, though you can access it via the Web. To send a first-class priority (same-day) message from New York to Los Angeles now costs US$25, plus 88 cents a word. (Plus whatever it costs to refill your meds--because who in their right mind would bother to send a telegram?) Western Union is still around too, though its primary customers appear to be Internet scam artists hoping to dupe suckers into wiring them money.
