The price of light is lower than the cost of darkness.
A quote from Arthur Charles Nielsen
(September 5, 1897–June 1, 1980)
He founded his company in 1923 in Chicago, Illinois, in order to give marketers reliable and objective information on the impact of marketing and sales programs. ACNielsen began expanding internationally in 1939, and now operates in more than 100 countries.
