Average minute audience (AMA) is a type of measurement that directly reflects the television audience size. It is calculated by averaging the number of viewers for each minute of
programming throughout the event. It is commonly used by broadcasters, advertisers, and researchers to evaluate the performance and popularity of TV content.
AMA can vary depending on the
target group, but generally the higher the value, the greater the popularity of the program. Target groups could include age, gender, ethnicity, religion, or any combination of these. AMA can also be reported for different
time periods, such as live, same-day, or
delayed viewing. The term "average minute audience" is a standard metric used in television audience measurement.

It reflects the ''average'' size of the ''audience'' on a ''minute''-by-''minute'' basis ''throughout the length of a program''. It is often used to compare the viewership of different programs or events, such as

Nielsen uses a sample of 40,000 homes and about 100,000 people that is
demographically representative of the population as a whole to estimate the AMA for various TV channels and programs.
Nielsen also provides other ratings metrics, such as rating, share, reach, and
gross rating point
In advertising, a gross rating point (GRP) measures the size of an audience that an advertisement impacts. GRPs help answer ''how often'' "must someone see it before they can readily recall it" and "how many times" does it take before the desired o ...

AMA is often used to compare the viewership of different TV programs or events, especially in genres such as sports, news, and
awards shows. For example, AMA can be used to rank the most-watched

s or events in a given year or season. AMA can also be used to measure the impact of social media or other factors on TV viewership. For instance, AMA can be used to analyze how Twitter activity influences the audience size of live TV events.
The AMA has some limitations as a measure of TV audience size. For one thing, it does not account for the quality or engagement of the viewership. For example, a program with a high AMA may have a lot of viewers who are not paying attention or who are switching channels frequently. Conversely, a program with a low AMA may have a loyal and attentive
fan base. Moreover, AMA does not capture the full extent of
