Today marks the 50th anniversary of The Marine Offences Act, which banned offshore radio stations- including the likes of Radio Caroline.
Pirate radio first gained popularity in the early 1960s when unlicensed stations began broadcasting music from offshore vessels - with around 22 million listeners.
One of the most famous was Radio Caroline, which broadcast from the Ross Revenge vessel.
Today the vessel is anchored off Bradwell in Essex and is no longer that rebel radio station. In May this year OFCOM announced Radio Caroline is being granted its first full-time AM broadcast licence.
