WPP said that performance was "well ahead" of the units' first half growth of 2.1%, but was down slightly from their 8.1% pace in the third quarter.
Those results, which were reported on a "constant currency" basis, performed better than WPP's overall revenues during the quarter, which rose 5.6%.
"This continuing improvement was driven largely by our uniquely global direct, digital and interactive businesses, amongst others comprising OgilvyOne, with global revenues of over $800 million, VML and Wunderman, with global revenues over $900 million," WPP reported.
