In a blow to the Audit Bureau of Circulations, Centaur Media has become the latest major publisher to adopt a multi-platform audience measure endorsed by PricewaterhouseCoopers.

Marketing Week, The Lawyer, Money Marketing, Employee Benefits and Fund Strategy will unveil their new combined digital and print weekly audience reach figures on 25 October.

Centaur managing director business publishing Tim Potter said: "Our audiences engage with us in many different ways but until now there has been no consistent audience measure in the markets we serve focused on the brand rather than a separate print, digital or event perspective.”
