PHD is a global media agency, founded in London in 1990, that helps brands grow faster than their competitors through strategic and creative media planning. Part of Omnicom Media Group, PHD provides global media planning and buying services for clients across markets. Its core offering combines data, technology, and human-centric principles to drive measurable outcomes, drawing on expertise and talent across markets and disciplines to deliver work with real impact. PHD gives clients access to Omni, Omnicom Group's marketing orchestration and insights platform, which houses Omni Studio — a proprietary global planning and collaboration platform that blends gamification techniques with strategic principles to drive innovation. Operating from over 100 offices in 74 countries, PHD serves some of the world's largest advertisers, backed by sophisticated research resources and advanced business intelligence tools. Recent business highlights include being named OpenAI's global media agency of record, and despite 37% of its client base — representing $4 billion in billings — going into review by end of 2024, PHD retained 85% of that business and earned its second consecutive Global Media Agency of the Year title from ADWEEK.
