In the 1930s, wirephoto machines of any reasonable speed were very large and expensive and required a dedicated phone line. en.wikipedia.org

The first wirephoto systems were slow and did not reproduce well. en.wikipedia.org

In the mid-1930s a technology battle began for less expensive portable wirephoto equipment that could transmit photos over standard phone lines. en.wikipedia.org

Wirephoto had also transmitted maps and charts from its inception, but these became especially valuable during war time. time.com
