Total persons/homes in a given population, such as TV Households in the U.S. Universe = 10 HH
Acronym for Designated Market Area. DMAs are a way of designating particular geographic markets, and are often ranked by size of population. As it applies in Strata: DMAIncludes all TV Homes: satellite, hard-wired cable, non-cable homes.Viewing reported to cable networks in the DMA could be in satellite or hard-wired homes. As it applies in Strata: CDMAHard-wired cable universe (excludes satellite and non-cable homes).

The audience expressed in numeric, rather than percent form. IMP = Rating(%) x Universe Also called Average Audience Projection. Also called Rating (000).
Gross Rating Points (GRPs) The sum of all ratings for all programs in a schedule. Gross Impressions (GIMPs)The GRPs expressed in numeric rather than percent form.
The number of different people/homes exposed at least once to a program or commercial across a stated period of time. Also called cumulative (cume) or unduplicated audience; can be expressed in full numbers or as a percentage.

At the local level, Nielsen measures television audiencesusing three different methodologies depending on the market.In the smallest markets (currently markets ranked above #60) diaries (see right) are sent out four times a year during “sweep” months (Feb, May, July, November). The broadcasters tend to schedule premieres, specials and original programming during these “sweep” periods, and this “hyped” data is used for buying and selling the rest of the year. Diaries are used to collect both viewing (who) and tuning (how many people) to programs and networks. The diary is the least accurate collection method. In the next set of markets (ranked 14-60), set meters areused to capture set tuning continuously all year, while diaries are still mailed out during sweeps to capture demographics(who is watching). These two methods are joined together to develop audience estimates in these markets.In the top markets (ranked 1-13), local people meters (LPM) are used to electronically capture both tuning and viewing. The LPM is considered the standard of measurement in the US today.
