Notes The term "billings" refers to the combined value of UK above-the-line advertising (including online) that is booked, placed and created by agencies on behalf of their clients. It should not be confused with agency income. No part of this report may be reproduced without the express permission of Campaign and Nielsen. Agency-client assignments are compiled from data supplied to Nielsen by agencies and media owners on a regular basis, alongside information published in the marketing press. Billings for Top 100 agencies are based on accounts handled on a creative or full-service basis. Agencies are listed according to their names and structures in 2016.
