As an
AM radio format in the
United States and
Canada, MOR's heyday was the 1960s and the 1970s. The 50,000-watt AM radio stations
WLW in Cincinnati, Ohio;
WJR in Detroit, Michigan;
WNEW in New York City, New York;
WCCO in Minneapolis, Minnesota;
KMPC in Los Angeles, California;
KIRO and
KOMO in Seattle, Washington;
WTIC in Hartford, Connecticut; and Canadian stations
CFRB in Toronto, Ontario and
CKNW in Vancouver, British Columbia, were known as "
full-service MOR" stations with scheduled programming other than the MOR music. Even though it was not a 50,000-watt station, WMAL in Washington DC achieved some of the highest ratings and revenue of all radio stations in the country by programming MOR music, news, sports, and very popular announcers. In time, as the listener demographic groups aged and popular music migrated to FM radio, MOR stations found themselves competing with
adult contemporary FM stations and AM stations broadcasting the
Music of Your Life and
adult standards formats. In response, most eliminated music and transmitted only news and talk programs; some continued to play MOR music until the early 1990s. MOR (or at least formats bearing a strong resemblance to MOR) were still available as late as 2013; the Memories/
Unforgettable Favorites network, a nationwide MOR satellite service, was available until 2006. Many of the styles and genres of music that had traditionally been heard on MOR formatted stations are currently heard on adult standards-formatted stations. The nationally syndicated
MeTV FM format, which brands itself as oldies, follows a format similar to MOR. ==Criticism==
