Apart from KMFM Ashford, each station was previously independent before being bought by the KM Group and rebranded.

Each area however still offers local advertisements and sponsorships (in the case of the DAB and online services, countywide adverts are heard).

Apart from Medway, from 2007 each station grouped with its neighbour (West Kent and Maidstone; Canterbury and Thanet; Ashford and Shepway and White Cliffs Country) to network programmes between 11am and 7pm.

The programmes were merged in April 2009 to create two groups with their own networked programming – West (Maidstone, Medway and West Kent) and East (Ashford, Canterbury, Shepway and White Cliffs Country and Thanet).

In September 2009, KMFM was given permission to network all its programmes apart from Monday to Saturday breakfast, and Sunday afternoons.

Initially, each station provided an independent service during peak hours from their respective newsrooms.
