In the UK, the idea of community-based services can be traced back at least as far as the original concept for BBC local radio in the early 1960s. Thereafter, various land-based unlicensed pirate radio stations (such as East London Radio and Radio AMY: Alternative Media for You) developed the idea further. As pirate stations proliferated during the late 1970s and early 1980s, these stations were joined by those broadcasting specifically to minority immigrant communities (such as the Afro-Caribbean and Asian communities, particularly in cities such as London, Birmingham, Bristol, Gloucester and Manchester). Although "community radio" remains synonymous with "pirate radio" for some people in the UK, most minority immigrant stations focused purely on specific musical genres and were operated (theoretically at least) on a for-profit basis. Community radio services in the UK are operated on a not-for-profit basis, with community ownership and control built into their structure.
