Nielsen Media Research and the Omnicom group have signed a five-year group contract to provide media information services to Omnicom agencies, including BBDO Worldwide, Creative Media, DDB Needham Worldwide, GSD&M, TBWA Chiat/Day, Advanswers and Martin Williams.
This is the second group contract with a major advertising agency announced in the last two weeks by Nielsen. Earlier this month, it signed a similar five-year tie-up with True North.
The Omnicom contract will provide the group's agencies with electronic access to all Nielsen's broadcast network, cable and syndication reports.
