When did fax machines begin widespread use?
The use of the fax machine to transmit images via For many years, facsimile machines remained cumbersome, expensive and difficult to operate, but in 1966 Xerox introduced the Magnafax Telecopier, a smaller, 46-pound (17 kg) facsimile machine that was easier to use and could be connected to any telephone line. Using this machine, a letter-sized document took about six minutes to transmit. The process was slow, but it represented a major technological step. In the late 1970s, Japanese companies entered the market, and soon a new generation of faster, smaller and more efficient fax machines became available. Hope that sheds some light on your question.
