How did the ratings come to be?

Arthur Charles Nielsen, Sr. (A.C. Nielsen) founded the A.C. Nielsen company in 1923. The company specialized in quality testing. They also offered consulting services regarding machinery and parts. The company struggled financially, nearly going bankrupt. They recognized that they needed to move into a different and more profitable direction. The company began focusing on market research and measuring sales.

Nielsen is often credited with aiding in the creation of various market research tools and concepts, including the market share concept. By 1942, the company had entered the radio audience measurement industry. A.C. Nielsen, Jr. joined the company in 1945. Under his guidance and forward-thinking, the company gained great efficiencies in the method used to collect data and provide measurements. By 1950, they began using their technologies to evaluate how people watched various TV shows. Currently the company tracks more than just television habits. As the market has changed, the company's tracking and measuring efforts have as well. They now also measure data related to smart phones, DVR selections and subscriber services, such as Netflix.
