KDKA's First Broadcast

This is KDKA of the Westinghouse Electric and Manufacturing Company in East Pittsburgh, Pennsylvania. We shall now broadcast the election returns. We are receiving these returns through the cooperation and by special arrangement with the Pittsburgh Post and Sun. We’d appreciate it if anyone hearing this broadcast would communicate with us as we are very anxious to know how far the broadcast is reaching and how it is being received…
