Country music has enjoyed mainstream exposure and success throughout the '60s and '70s in the United Kingdom. However, this somewhat diminished in the '90s and 2000s. Though, there have been exceptions such as Garth Brooks and Shania Twain in the '90s (particularly the latter) and Taylor Swift, Carrie Underwood, Lady Antebellum and the Dixie Chicks in the 2000s. Crossover hits (in terms of singles and albums) within the country genre are few and far between and have been since the '80s. There are some British country music acts and publications. Although radio stations devoted to country are among the most popular in other Anglophone nations, none of the top 10 most-listened-to stations in the UK are country stations, and national broadcaster BBC Radio does not offer a full-time country station (BBC Radio 2 Country, a "pop-up" station, operated four days each year between 2015 and 2017). The BBC does offer a country show on BBC Radio 2 each week hosted by Bob Harris. UK Country music is overseen by the British Country Music Association.
By the end of World War II, "mountaineer" string band music known as bluegrass had emerged when Bill Monroe joined with Lester Flatt and Earl Scruggs, introduced by Roy Acuff at the Grand Ole Opry. That was the ordination of bluegrass music and how Bill Monroe became to be known as the "Father of Country Music." Gospel music, too, remained a popular component of bluegrass and other sorts of country music. Red Foley, the biggest country star following World War II, had one of the first million-selling gospel hits ("Peace in the Valley") and also sang boogie, blues and rockabilly. In the post-war period, country music was called "folk" in the trades, and "hillbilly" within the industry. In 1944, The Billboard replaced the term "hillbilly" with "folk songs and blues," and switched to "country" or "country and Western" in 1949. https://www.youtube.com/watch?v=hyNAvdnZ5Ec
