Are telegraph machines still used?
Although the telegraph that Samuel F. B. Morse successfully tested in 1837 is no longer in use today, its fall did give rise to many other forms of long distance communication. For example, wireless telegraphy, also known as radiotelegraphy or radio, is still a very important part of society.
