Wirephoto
（重定向自Radiophoto）
Wirephoto or telephotography is the sending of pictures by telegraph or telephone.
Western Union transmitted its first halftone photograph in 1921. AT&T followed in 1924, and RCA sent a Radiophoto in 1926. The Associated Press began its Wirephoto service in 1935 and held a trademark on the term AP Wirephoto between 1963 and 2004. The first AP photo sent by wire depicted the crash of a small plane in New York's Adirondack Mountains.
