About

Zenith plans and buys media, and publishes the forecasting and audience research that sits behind that work — its Global Intelligence practice puts out publications on category shifts such as travel becoming a digital experience or brand experience driving recovery in the alcohol sector. Its client work spans social, commerce and brand campaigns across markets, and it runs local Zenith sites for Australia, Austria, Germany, New Zealand, Norway, Poland, Spain, Switzerland, Taiwan, the UK and the USA.

The agency is part of Publicis Groupe, under Publicis Media.

Zenith Canada announced Ian Martins as executive vice president and managing director in December 2023, reporting to Alastair Taylor, chief executive of Publicis Media. Martins framed the appointment around a shift in what clients want: "The industry is witnessing a shift, and clients are looking for agencies that can provide more than just media services." Taylor called Zenith "a special brand with an amazing legacy."
