Nobody knows who wrote the first letter or when, but we know that 4,000 years ago in Anclent Egypt people carried letters by hand over hundreds of kilometers. Very few people could write, so there were special people, called scribes, who wrote letters for everyone else. The first stamp didn't appear until 1840 and it cost just one penny. Nowadays one of the original stamps cost €375. Letter writing was so popular in the 1840s that people delivered the post several times a day. An American company - Remington and Sons - made the first typewriter in 1871. All the letters in the word 'typewriter' were on the top line of the' keyboard so that salesmen could demonstrate the machine more easily. Amazingly, the letters are still in the same place on the modern computer keyboard! In 1875, when Alexander Graham Bell demonstrated a fantastic new invention called the telephone, nobody was very interested in it. The first fax machine appeared at around the same time, but it was so enormous that no one wanted one in fact, fax machine didn't become popular for another hundred years.
