In the two largest markets -- New York and Los Angeles -- sample sizes will grow by 300 homes each next year. Another eight markets -- Charlotte, St. Louis, Chicago, Philadelphia, San Francisco, Boston, Atlanta, and Phoenix -- will follow, with each seeing their sample size increase by 200 homes in 2015.
Five previously announced markets -- which include Dallas, Washington, D.C., Houston, Miami, and Denver -- will each see an increase of 200 homes this year.
Separately, Nielsen will expand samples by almost 50% -- around 200 homes -- in the 31 set-meter markets over the next two years.
In a move that will help small TV markets, Nielsen announced earlier this year plans to install code readers in select diary markets to bring year-round electronic measurement. There are 25 Nielsen local people meter markets; 31 Nielsen set-meter markets and 154 Nielsen diary-only markets.
Said Matt O'Grady, executive vice president/managing director of local media of Nielsen, in a release: “With this supplemental expansion, our local media clients will see increased stability through expanded metered samples and electronic measurement to diary markets that never had metered samples.”
