The molded plastics industry attracted the radio and electronics industries to the Boonton area. In the 1920s, the burgeoning radio industry created a large demand for molded parts. Richard W. Seabury organized Radio Frequency Laboratories to exploit that new field. More than a half dozen radio and electronics firms were later formed as spin-offs, and recognized internationally for the excellence of their products. Radio engineers had respect for the Boonton Radio Co., located in nearby Rockaway, which manufactured a high-quality test instrument known as a Q meter, still used by hobbyists today. Most of those companies have been bought up and are now divisions of larger corporations and have relocated elsewhere, having undergone name changes in many cases. The Boonton Radio Co., for instance, was purchased by Hewlett-Packard. RFL Industries, Aircraft Radio Corporation, Measurements Corporation, and Ballantine Laboratories are among those that contributed materially to the prosperity of the area.
