KMMJ Radio:

One of Clay County's most prominent citizens, M.M. Johnson, was one of our most innovative and enterprising residents as well.  He Founded the Old Trusty Incubator factory located in Clay Center, Nebraska

Over the years the business further expanded and diversified the family's holdings to include one of the earliest radio stations in the state, KMMJ (with call letters derived from the initials of the senior Johnson) which went on the air on November 30, 1925. With programming "geared to the families of agricultural communities" the station became widely known for its popular entertainment features. Among the most notable KMMJ entertainers were Jimmy Atkins, Robert Taylor and Lawrence Welk. Through the radio station airwaves were advertised a great variety of products bearing the OLD TRUSTY name. In addition to incubators and brooders, products such as coffee, gasoline, paints, varnishes and a variety of poultry products were offered. In 1936 the M.M. Johnson Company, licensee of KMMJ, was acquired by the Town and Farm Company and in January 1939 the studios of KMMJ were relocated to Grand Island, NE, bringing to a close over four decades of familiar OLD TRUSTY enterprises in Clay Center. In June 1977, the Clay County Historical Society obtained an agreement with the City of Clay Center for acquistion of the old KMMJ building site and on July 19, 1979 ground breaking ceremonies were held to begin construction of the Clay County Museum. Appropriately, the museum's Grand Opening on May 25, 1980 was marked with a live, remote broadcast by radio station KMMJ. On September 10 and 11, 1983 the Clay County Historical Society initiated the First Annual OLD TRUSTY Antique Engine and Collectors Show as a fundraising event for the continued growth and prosperity of the Museum as well as a means of increasing awareness of Clay County's important past
