Sainsbury’s has confirmed the reappointment of PHD to its GBP60 million UK media planning and buying business. PHD beat the Group M agencies Maxus and MediaCom, as well as Publicis Groupe’s ZenithOptimedia, to retain the account. The supermarket decided to continue its 19-year relationship with the Omnicom shop after a three-month review process. The news capped a week of celebrations at PHD, which was marking its 25th anniversary.
