Around the 1920s, phonographs became more public than just personal home devices. Here, a customer at Loewy’s 1 cent arcade (14th street, New York) drops a cent in the slot to listen to a phonograph record. Not only did this increase the popularity of the phonograph, it also increased the size of the industry. In addition, what the man is using to listen to the record is a pair of small phonograph horns. These were then named "ear-trumpets" which set the model for modern headphones.
