Arthur Charles Nielsen, Sr. (September 5, 1897–June 1, 1980) was an American market analyst of Danish descent. He was the founder of the eponymous ACNielsen company in 1923, and in doing so advanced the new field of marketing research. This involved (1) test marketing new products to determine their viability prior to costly mass marketing and production, and (2) measuring product sales at a random sample of stores to determine market share. Careful statistical sampling is crucial to validate this process. The techniques developed by Nielsen were especially important for the efficient operation of a market prior to the introduction of computerized digital networks that in the 1990s enabled continuous and comprehensive monitoring of sales by product retailers. Nielsen was also a pioneer in developing methods of measuring the audience of radio and television broadcasting programs, most notably the Nielsen Ratings. is the 248th day of the year (249th in leap years) in the Gregorian calendar. ... 1897 (MDCCCXCVII) was a common year starting on Friday (see link for calendar). ... is the 152nd day of the year (153rd in leap years) in the Gregorian calendar. ...
