The onset of the Great Depression led to greatly diminished demand for Atwater Kent's expensive radio sets. The company adjusted to consumer demands by building smaller, tabletop radio sets, but Kent was not one to compromise on quality. A drop in demand was compounded by the expiration of patents on the superheterodyne circuit—which led directly to the proliferation of inexpensive All American Five radio designs. New firms could now easily enter the radio manufacturing market without the same level of capital investment Kent had put into his production process, which relied on heavy metal presses for the relatively large Tuned Radio Frequency (TRF) type radio chassis the firm produced. Kent dissolved his design engineering facility in 1931, and shuttered his radio factory in 1936. A major local competitor, Philco, acquired the closed plant and built its refrigerators there.
