A hundred years ago, if you wanted to send a message to Europe fast, you would use the WWW–that is, RCA’s World Wide Wireless service. You could send Marconigrams at various rates, depending on country. Messages to England were 17 cents a word, up to 36 cents per word to Germany.

You could call and have a uniformed messenger pick up your message, or you could take it in person. Three locations in Manhattan were open 8 AM to 8 PM. The location at 64 Broad Street was always open.
