LONDON: Despite languishing in the lower half of UK media agency rankings for 2007, WPP Group unit Mediaedge:cia won the 'fastest growing' accolade with a roistering 45.9% increase in annual billings to £350 million ($682.89m; €463.22m).

The annual UK media agency rankings, calculated by Nielsen Media Research, see fellow WPP shop MediaCom retain its numero uno position for a sixth year, lifting billings by 6.4% to £971m – tantalisingly close to the beckoning billion.

No change either for second-placed Omnicom agency OMD, up 7.5% to £846.7m; while another WPP agency, MindShare, clung to third place with £721m despite a 2.5% billings blip.

The remaining top ten agencies are  …

4.  Starcom (Publicis Groupe) £656.5m

5.  Carat (Aegis Group) £647m

6.  ZenithOptimedia (Publicis Groupe) £571m
7.  Mediaedge:cia (WPP Group) £350m

8.  Initiative (Interpublic Group) £274.7m
