It's a pretty amazing piece of not-particularly-high technology. Western Union first sent a halftone photo in 1921, and Associated Press started its WirePhoto service a couple years before this film was made. Love the scenes of the front page being made up with lead type and mattes. Poor ol' newspapers.
