frequencies during this transition, WSM-FM did not, and the station announced that it was "signing off temporarily" on June 1, 1946, in order to install the new transmitting equipment. In 1947, as part of a nationwide reallocation, WSM-FM was reassigned to 103.3 MHz. Following years of unprofitability, National Life decided to shut down WSM-FM permanently on March 15, 1951, and returned its license to the FCC for cancellation, because few area households had FM radios and commercial potential was lacking. John H. DeWitt, now WSM president, issued a statement reviewing the ten years of operation, noting "We have continued this operation in spite of the fact that the audience was very disappointing and that the station operated at a complete loss during the entire period. This loss has amounted to nearly one quarter of a million dollars to date." To partially make up for the loss of WSM-FM's musical programming, a daily noontime program of one hour of classical music was announced for the AM station. National Life's original station, WSM (which it owned until 1981), and television station WSM-TV (now WSMV-TV), established in 1950, were both commercially successful. In 1967 National Life returned to FM broadcasting when it purchased WLWM and revived the WSM-FM call letters the next year.
