At first, Ocean broadcast two distinct services for the east and west of its service area with a further service for the Winchester area launching in December 1987. The West service was relaunched as Power FM (later Capital South Coast) a year later while the north and east services (The Light FM and Ocean Sound) merged in 1992.
Both 2CR and Ocean underwent various ownership changes until its current owners Global Radio rebranded the stations as Heart on 22 June 2009.
On 21 June 2010, Global Radio announced it would merge both stations as part of plans to reduce the Heart network of stations from 33 to 16. The new station began broadcasting from Segensworth, near Whiteley on Friday 30 July 2010, leading to the closure of studios in Bournemouth.
