Nielsen's Sampling Methodology
- Nielsen measures US TV viewership using a statistically designed panel of about 100,000 people in 42,000 households.
- This panel is demographically balanced to mirror the US population, ensuring a margin of error less than 1%.
PPM Devices Track Viewing Seamlessly
- Nielsen uses PPM devices that detect inaudible network tones to track what each household member watches without viewer effort.
- These devices upload anonymized data nightly, ensuring streamlined, accurate audience measurement.
Understanding Nielsen TV Metrics
- Key Nielsen metrics include total viewers, household rating (% of all TV homes), and household share (% of TVs in use tuned in).
- Example: Super Bowl 59 had 127.7 million viewers, 41.7 household rating, and 83% share.
