Core was originally owned by GWR Group (which became GCap Media and then Global Radio after the station's closure).

The presenter lineup prior to the changes was Allan Lake, Nicola Bonn, Sophie Bruce, Philippa Collins, Nick Ludlow, Tim Cocker, Ben Moss, Val Mellon, Sally Hudson, Ben Glover and Kevin Hughes.

The final song to play on the station was "So Long & Thanks For All The Fish" by Hilary Summers, Kemi Omniyi & The R'svp Voices.

The station relaunched its website in late 2006 with extra content, a music download service and information on currently playing and upcoming tracks.

The ten competed in a variety of tasks to demonstrate their presenting skills, whilst gathering friends on MySpace.

Core's Programme Manager, Bern Leckie, decided who stayed in the competition based on their performance.
