The new data currency, which has been in intensive development in consultation with the industry, will (for the first time) incorporate phone, tablet, desktop and print platforms for publishers.
Besides measuring publisher brands reach across each of these mediums, the new measurement also combines and de-duplicates the data to introduce a total brand reach across all platforms.
Overall, the UK's newsbrands and magazine titles have a total market reach of 48,114 per month.
"This new, joint industry currency (JIC) replaces NRS which was no longer fit for purpose in a
digital world where the way readers consume their media is changing at an incredible pace," Jan Gooding, chair of Pamco said. "The new data offers greater visibility and accountability to both publishers and advertisers, giving the industry renewed confidence in its advertising trading currency."
The new JIC draws on the latest passive measurement techniques, combined with 35,000 face-to-face interviews.
"Having one single de-duplicated view across all platforms has been top of our wish list for many years and Pamco has delivered this to the benefit of publishers, their media agencies and advertising customers," Paul Bainsfair, director general of the IPA, said.
For Time Inc chief executive, Marcus Rich, the new metric will provide the title with a "robust rationale" for including all its publisher platforms in agency pitches to clients.
A heartening finding from the new study is that reach of publisher content among young audiences is high, with 93% of 15- to 34-year-olds viewing published content each month, Simon Redican, chief executive of Pamco pointed out. "We are confident that Pamco will reveal further insights as users explore the data", he added.
In total, the UK's newsbrands have a total monthly brand reach of 46,071 with the highest reach still residing in print (31,559 per month) followed by phone (28,200), desktop (17,306) and tablet (9,460).
