Ever wondered about the evolution of fax and business? How they became so mutually inclusive? Well, there is definitely a certain pattern when it comes to fax and business, but in order to understand where it all started and how it all started, you need to make sure that you understand the history of the fax itself and how crucial it has been to communications as a whole. Fax machines themselves were actually not viewed as essential pieces of equipment until the late 20th century. Before that, methods of communication were the telegram and the letter. The fax machine was however invented before the telephone, by Alexander Bain. Bain wanted to send information fast, via an electronic impulse so that people could get letters much faster than via the postal service. He succeeded in inventing this machine, but it was not developed until much later.
