 Initially there were no specific standards for stations making general broadcasts, until the Department of Commerce, which regulated radio at this time, adopted regulations effective December 1, 1921 for a new classification of "broadcasting stations".Two transmitting wavelengths were set aside for this new service—360 meters (833 kilohertz) for "entertainment" and 485 meters (619 kilohertz) for "market and weather reports"—and stations providing programs intended for the general public were now required to obtain a Limited Commercial license that included a broadcast service assignment.The University was issued its first broadcasting station authorization, for 485 meters, on March 23, 1922, with the randomly assigned call letters of WEW.
