Countrywide Porter Novelli has snapped up consumer-tech independent Fodor Wyllie Associates to boost its Convergence Group offerings.
The deal - for an undisclosed sum - sees Fodor Wyllie join CPN's fast growing international practice, Porter Novelli Convergence Group (PNCG).
Fodor Wyllie as a brand name will no longer exist, with the agency assuming the convergence group banner.
Co-founders Grace Fodor and Jean Wyllie will join the PNCG board, while managing director Tom Watson becomes PNCG UK managing director.
CPN chairman Peter Hehir, who is also chairman of Porter Novelli International, said the acquisition strengthens the group's offerings throughout the UK and Europe.
'Bringing Fodor Wyllie into the picture has really stepped up the division's consumer and new media capabilities,' he said.
'What we can bring to Fodor Wyllie is the international strength of the convergence group.'
Fodor confirmed its 34 staff will stay with the agency through the merger - increasing the PNCG staff number to over 45 - and will be split between Fodor Wyllie's Kingston office and CPN's London office.
Fodor said they will also be looking to recruit at least five people from account manager to account director level over the next few months.
PNCG was founded a year ago with CPN's acquisition of US-based hi-tech PR firm Copithorne and Bellows.
The group earns pounds 34m in annual revenue - with another pounds 1.7m added from the acquisition of Fodor Wyllie.
