Mars is also expected to move the global advertising account for Twix out of TBWA and into BBDO New York.
Additionally, the Mars, Skittles and Starburst brands have been moved out of TBWA into Omnicom-owned DDB.
TBWA Worldwide had a 10-year relationship with Mars. The network added 14 new global creative assignments from Mars in 2002 after the network split from Cadbury.
Just a year ago, TBWA\Worldwide retained the global Twix business, and picked up the US portion of the account, after a pitch against SapientNitro.
