Luxury jeweller Tiffany & Co has appointed MEC to its global media planning and buying account worth $100m, sources have confirmed.

MEC beat Omnicom Media Group and sister-agency MediaCom to the account, which it will run from New York.

Ark Advisors managed the review, which kicked off back in July.

Tiffany’s media planning and buying was previously split among several regional agencies – EMEA handled by incumbent UM, Merkle in the US and Carat in APAC.

Ogilvy & Mather Worldwide won the company’s global advertising account back in March which was also organised by Ark Advisors.
