Sir Martin Sorrell’s WPP Group has taken a stake in US advertising and mobile search company JumpTap, as it looks to bolster its position in digital media.
The purchase by WPP Digital, for an undisclosed sum, follows other recent investments in the digital field, including internet advertising agency Spot Runner and online game publisher Wild Tangent.
JumpTap, which is based in Massachusetts and whose clients include Virgin Mobile USA, had gross assets of $3m (£1.52m) at the time of the deal. WPP has acquired a 2.5% stake in the company.
Meanwhile, Aegis has acquired The Netherlands’ largest independent full-service market research business Interview-NSS.
Interview-NSS, which has gross assets of £5.3m, specialises in polling, media and branding research.
Aegis chief executive Robert Lerwill says the purchase will prove an excellent fit with Synovate, Aegis’ market research arm.
