On Tuesday, a
MediaDailyNews story entitled "Interpublic Signs TiVo Ratings Deal, No Comment From Nets" wrote that a sample of 20,000 TiVo homes for measuring second-by-second data was based on
"a considerably smaller sample than the Nielsen national pool." In fact, Nielsen ratings are based on a pool of homes that is about half that size. However, the TiVo StopWatch service gauges behavior
from a universe of 4 million-plus homes, compared to Nielsen's attempt to produce ratings for all American TV homes.
