In mid-1919, AT&T ran advertisements in general circulation publications, which featured the advances the company had made in developing radiotelephony during the previous four years.
The graphic at the top of the advertisement is a collage of three AT&T achievements mentioned in the ad. In the center is a view of the crowd at the Victory Way Loan drive in New York City, which in May, 1919 listened to distant speeches carried by telephone and radio. The two radio towers on the left belong to the U.S. Navy's NAA in Arlington, Virginia (located across the Potomac River from Washington, D.C.), which in 1915 had transmitted speech to the Eiffel Tower in Paris, displayed on the right. Finally, across the top is the curve of the Atlantic Ocean with three ships -- the Arlington signals had crossed this ocean in 1915, during World War One radio helped protect Allied shipping.
