system, telephone lines and radio broadcasting was used in connec- 

 tion with reporting a football game played in Chicago in the fall of 

 1922. By means of high quality transmitters and amplifiers located at 

 the football field, announcements of the plays and the applause of the 

 spectators were delivered to a circuit extending to the toll office in 

 Chicago. This circuit was connected there to a toll line to New York 

 where it delivered the telephonic currents to a radio broadcasting 

 transmitter. In Park Row, in New York City, was located a truck on 

 which was mounted a radio receiving set arranged to operate a public 

 address system. By this means the reports of the plays of the foot- 

 ball game in Chicago were delivered to a large crowd in the streets of 

 New York.
