From 1919 to 1921 the hotel became the home of the Greater Waterloo Association. It was the result of a merger of four organizations that had worked separately to improve and develop the city. Black Hawk Broadcasting Company established radio station KWWL in the hotel in 1947, and television station KWWL in 1953. Studios for both stations were located in the hotel until 1958. The building was listed on the National Register of Historic Places in 1988. The 250-room hotel has been converted into a 90-unit apartment building.
