Customers use Nielsen Media Research's television audience research information to buy and sell television time as well as to make program decisions. That information is the currency in all the transactions between buyers and sellers, which adds up to approximately $44 billion in national and local advertising spending in the U.S. each year. Without an independent, third-party measurement system embracing the highest standards of accuracy and integrity, the television marketplace could not function effectively. Assuring the value of this currency is the Number One priority of Nielsen Media Research.

Nielsen Media Research provides its services to a complex and highly competitive marketplace. We are sometimes referred to as an umpire or referee faced with conflicting demands from competing groups of customers.
