海賊放送
Pirate radio met with increasing opposition, especially from the authorities in the form of the Department of Trade and Industry (DTI). It had claimed since the 1970s that pirate radio caused interference to licensed broadcasters and could interfere with frequencies used by emergency services. Nonetheless the growth of pirate radio in the 1980s was so rapid that at one point pirate radio operators outnumbered legal broadcasters and in popularity.
