Two new Top 40 stations launch in major Canadian cities, as CFTR Toronto abandons its simulcast of beautiful music CHFI-FM for Top 40 early in the year, and in Ottawa, CKPM becomes CFGO on June 21.
WDRQDetroit, having debuted the previous year as a news/talk station, flips to Top 40, as does WAAM in nearby Ann Arbor (dropping its longtime MOR format). Detroit also loses a Top 40 station on April 25, 1972, as WKNR changes from "Keener 13" to beautiful music as WNIC, simulcast with its FM sister (formerly WKNR-FM).
Metromedia sells off their Cleveland stations, WHK and WMMS, to the Detroit-based Malrite Communications Group. After protests and pleas from WMMS' devoted following, Malrite vows to maintain the FM stations' progressive rock format, and relocates their corporate headquarters to Cleveland. Farther west in Toledo, progressive rock fans get a Christmas gift as WCWA-FM becomes WIOT-FM on Christmas Day.
