OW soon will talking moving pictures be on tap in every home that has a radio set? Is this form of entertainment "just around the corner," or is it a fancy that will lay on the shelf along with perpetual-motion machines and rockets that will shoot to the moon? Having witnessed a demonstration of the new movietone apparatus, we are rather inclined to predict that it wont be long now until Mr. John W. Citizen can tune in on Station U. S. A., pull down his movie screen and spend an evening with Hollywood's finest or watch the antics of the Winter Garden chorus without tramping threequarters of a mile thru the slush to his favorite theater.
The movietone certainly bridges a huge gap in the trail. Here we have pictures and sounds developed on the same strip of film, and action and speech recorded simultaneously, thus insuring perfect harmony. If the next step, that of perfecting the apparatus to broadcast the results is successfully accomplished, this dream becomes a reality.
