The account will remain with incumbent agencies Universal McCann, which handles the account in the US, the UK and Europe, and WPP Group's MindShare in South America.
Motorola said the company began the review of the account in September 2000 after creative work was consolidated into Ogilvy & Mather New York, following a pitch against fellow roster agencies, McCann-Erickson Worldwide and Leo Burnett.
In the spring, Motorola slashed its global advertising budget by around $250m (£178.7m), or 70%, scaling back from a major global brand campaign after consolidating into O&M.
