The second was developed by Dadson Industries, Inc. Dadson's vender (name the industry uses for vending machines) was first used in a NY subway in December 1946 to sell paperbacks published by New York's Pocket Books. In January 1947 a Billboard article quotes a Pocket Book executive as saying Dadson has no right to sell the books. He goes on to say only Automatic with their Book-o-Mat is under contract to sell Pocket Books. There is a picture in the May 1947 Popular Mechanics of a machine which is not named but meets the description of the Dadson.
