The web measurement firm Quantcast has appointed ex-Yahoo! MD Philip Macauley to lead the company's operations and expansion into the UK market. Macauley spent ten years at Yahoo! , where he was most recently Director of Business Development and Commercial Relations. His tenor at the Internet giant saw him take on various "senior roles" including "driving media agency relationships as Agency Sales Director and leading the company's publisher efforts as Head of Publisher Partnerships." All of which would appear to make Macauley a very good fit for Quantcast.
