London's stalwart pirate radio underground has been an essential tool for the growth of electronic dance music since the mid-80's, specifically Acid House, Breakbeat Hardcore, Jungle/Drum'n'Bass, Ragga and now Grime/Dubstep. It provides, free of charge to the listening public, a wealth of brand new music, often produced right in their own neighborhoods, that mainstream radio either can't or won't play (although that's changed greatly in recent years), as well as offering a community rallying point culturally. There are a few perspectives of pirate radio, one from The Powers That Be concerning "theft" of the airwaves and another that's more about the music.

Another London news clip, this one from 1994, the early days of Jungle, with squareness in full effect:
There's a sense of mystery surrounding pirate radio that lies in its clandestine nature - both musically as well as physically.

Throughout the "Second Summer of Love", as the heady Acid House-drenched summer of 1988 is often called, pirate radio was the beacon in the night, guiding clubland refugees to the nonstop party. This UK documentary from '94 shows a bit more of a balanced viewpoint, particularly showing the establishment's skewered views in stark light.
