Meet the leaders of today’s Nielsen.

Our History
Founded in 1923 by Arthur Charles Nielsen, Sr., Nielsen introduced consumer marketers to many innovative research methods and techniques that today are standard industry practice, including the first objective and reliable methodology for measuring retail sales and competitive market shares. Mr. Nielsen also founded our sister company, Nielsen Media Research, the global leader in television audience measurement and other media research services.

The Nielsen Code
In 1931, Arthur C. Nielsen, Sr. wrote the Nielsen Code, defining the principles that would guide Nielsen to global leadership in marketing research. The Code remains relevant today and continues to guide our business. 

The VNU Advantage
In 2001, Nielsen became part of VNU, a world leader in marketing information, media measurement & information and business media.
