The new internet measurement panel, known at 'Net-Metrix-Tracking - powered by Nielsen Online', combines two existing panel products -- NetView from Nielsen Online and Net-Metrix-Tracking from Net-Metrix.
The partnership will be comprised of around 4,000 '@home' panellists, with the aim of expanding that number to 10,000 by mid-2009 with an additional '@work' panel of 1,500 people also included.
Manuel Daehler, joint chief executive of Net-Metrix, said: "The co-operation between Net-Metrix and Nielsen means Swiss clients will have access to a broad suite of internet measurement tools like never before.
"Futhermore, Switzerland will have consistent and recognised internet panel data that will benefit advertisers, agencies and publishers alike and will help to promote online as an important part of the media and advertising mix."
