Soft drink giant The Coca-Cola Co is looking at consolidating its media planning and buying into one agency, an account estimated to be worth US$300m.

"We're looking to one firm to handle the media planning and (buying) for the entire portfolio of beverages -- soft drinks, juices," said Coca-Cola spokesman Mark Martin.

Currently the media planning and buying for Coca-Cola is been handled by Starcom MediaVest and Universal McCann.

These two groups have already been invited to make presentations for the campaign in October, along with MindShare and Carat.

A decision on the account is expected in late October.
