(CNN)--Arthur C. Nielsen Junior, the man behind the T-V ratings firm, died Monday at his home in Winnetka, Illinois.
His father invented the system that measured television viewing habits -- but Nielsen was responsible for its growth.
Nielsen became the company's president in 1957, took over as chairman in 1975 and then retired in 1983.
Nielsen was 92-years-old.
