This service would be dominated by almost constant rebrands.
The station was an ILR (commercial radio) service which operated on AM & FM to the Reigate area of Surrey.
Radio Mercury & its neighbouring service 'County Sound Radio' merged. Mercury began broadcasting countywide on FM, whilst County Sound did likewise on AM.
County Sound was rebranded to 'Mercury Extra'. The 'Extra' was a mixed format of rolling news by day, and gold/easy listening music overnights.
With the loss of the Guildford licence to UKRD, the service continued broadcasting solely to Reigate.
The service dropped the rolling news part of the format, resulting in another name change.
A change of owner (DMG Radio) would see the service rebranded to match their Essex AM service.
Another change of ownership saw another rebranding.
The service ceased broadcasting to Surrey in January 2011.
