correctly, so the newspaper asked the regional Radio Inspector, S. W. Edwards, to have it changed to something more phonetically distinct, requesting WKL or WWW. Neither of these call signs was available, so one similar to the paper's request, WWJ, was assigned on March 3, 1922. Effective December 1, 1921, the U.S. government for the first time adopted regulations formally defining "broadcasting stations". The wavelength of 360 meters (for which WBL and eight other stations already held licenses) was designated for entertainment broadcasts, while 485 meters (619 kHz) was reserved for broadcasting official weather and other government reports. On March 3, 1922, WWJ was granted permission to transmit on 485 meters, in addition to its original 360-meter assignment. 1922 saw a rapid expansion in the number of broadcasting stations, most sharing the single entertainment wavelength of 360 meters, which required progressively more complicated time sharing schedules among stations in the same region. That May the News bristled at having to suffer the "handicap" of being required to give up some airtime to its competitor, the Detroit Free Press, which had, in the words of the News, decided to "break in" by establishing its own station, WCX (now WJR). A front page "explanation" in the News complained about having to reduce its schedule of "unique, wholesome and delightful entertainment". In late September 1922 a second entertainment wavelength, 400 meters (750 kHz), was made available for "Class B" stations, which had higher powers and better quality equipment and programming. Both WWJ and WCX qualified to use this new wavelength, on a timesharing basis. In early 1923 the United States further expanded the broadcast station allocations into a continuous band from 550 to 1350 kHz, with stations now using a single frequency, no longer having to broadcast entertainment and official reports on separate frequencies. Under the new allocations the Class B frequency of 580 kHz (516.9 meters) was designated for use by qualified stations in the "Detroit/Dearborn" area, and both WWJ and WCX were assigned to this frequency. In January 1925 WWJ was reassigned to an exclusive Class B frequency, 850 kHz (352.7 meters). A series of reassignments followed, as the government struggled to structure the broadcast band to accommodate an increasing congested environment. On November 11, 1928, the Federal Radio Commission implemented a major AM band reorganization, under the provisions of its General Order 40. This reallocation divided stations into three classes,
