The history of BASCA can be traced back over 65 years.
The Composers Guild of Great Britain (CGGB) formed in 1944 to represent the interests of classical composers, including composers for film. The British Songwriters Protection Guild of Great Britain was founded in 1947, later becoming the Songwriters Guild of Great Britain, then the British Academy of Songwriters, Composers and Authors (BASCA). In 1976, the Association of Professional Composers (APC) was founded to exclusively represent professional composers - predominately media composers. In the mid-90s the three guilds began to work more closely together through the Alliance of Composer Organisations (ACO). By 1999 the original three guilds had amalgamated to become the British Academy of Composers and Songwriters.
In 2009, the Academy re-branded as the British Academy of Songwriters, Composers and Authors, having the acronym of BASCA once again.
