How do I become a "Nielsen family"?
Nielsen Media Research cannot accept  volunteers for its ratings service. To be statistically accurate it is essential that our  sample be the result of random selection. Every household in the United States has an  equal chance of being selected, no matter where it is located. And, the random nature of  the sample ensures that people of all backgrounds and all ages can be included. If Nielsen  Media Research accepted volunteers, the composition of the sample might be affected. Our  clients – broadcast and cable television networks, local television stations and  cable systems, program producers and advertisers – use the information we provide to  help make decisions about which programs will be on the air. Our customers would not be  able to rely on the information to make appropriate decisions.
Since we do pick our sample on a random  basis, you do have a chance to become a Nielsen Media Research household. However, it can  only happen from our contacting you.
