, ask homes to participate in filling out a diary of the programs watched in their home for a one-week period. The Nielsen sample included roughly 1,700 audiometer homes and a rotating board of nearly 850 diary respondents by the early 1980s. Nielsen launched its Nielsen Homevideo Index (NHI) in 1980 to measure cable, pay cable, and VCRs, and the NHI began offering daily cable ratings in 1982. Nielsen's continued to advance with steady changes into the mid-2000s (decade). Along with changing their counting methods, Nielsen also started emphasizing their sample in 2003 in reaction to census shifts and requests from some industry sectors. Nielsen's automated Local People Meter (LPM) technology was introduced in New York and Los Angeles. The LPM improved the method of measurement from active and diary-based to passive and meter-monitored. More importantly, the LPM provides accurate measurements to particular local markets, verse a nationwide sample from the People meter. While diary-based surveys concentrated on quarterly sweeps periods, the industry has been pushed toward year-round measurement, due to the automated LPM system. In 1996 Nielsen Media Research began tracking computer, internet, and video game usage through telephone surveys. Nielsen Media Research is a sister company to Nielsen NetRatings, which measures Internet and digital media audiences through a telephone and internet survey, and Nielsen BuzzMetrics, which measures Consumer-Generated Media. Nielsen also conducts market research for the film industry through National Research Group (NRG). In September 2018, Nielsen acquired SuperData Research, an industry analysis firm that deals with tracking viewing habits within the video game and

in the United States using a rating system. Nielsen is no longer accredited by the Media Rating Council (MRC). Nielsen Media Research was founded by Arthur C. Nielsen, a market analyst who started his career in the 1920s with marketing research and performance analysis. The company subsequently expanded into radio market analysis in the late 1930s, culminating in the Nielsen Radio Index in 1942, which was meant to provide statistics as to the markets of radio shows. The first Nielsen ratings for radio programs were released the first week of December 1947. They measured the top 20 programs in four areas: total audience, average audience, cumulative audience, and homes per dollar spent for time and talent. In 1950, Nielsen then moved to television, developing a rating system using the methods he and his company had developed for radio. That method became the primary source of audience measurement information in the US television industry. In September 2020, Nielsen started compiling a weekly Top 10 list of most-watched shows on streaming platforms.

Ratings/share and total viewers

The most commonly cited Nielsen results are reported in two measurements: ratings points and share, usually reported as: "ratings points/share". There were 119.6 million TV homes in the U.S. for the 2017–18 TV season (Nielsen's National Television Household Universe, or Households Using Television, HUT). Nielsen re-estimates the number of television-equipped households each August for the upcoming television season. The rating of a program is a fraction of the HUT. It is calculated as RTG = HUT × SHARE where HUT (or PUT when measuring demos) is Homes Using Television and SHARE is the percentage of TV sets in use which are tuned to a particular show. Share is the percentage of television sets in use, Households Using Television (HUT) or Persons Using Television (PUT) who are tuned to a specific program, station or network in a specific area at a specific time. For example, Nielsen may report a show as receiving a 4.4/8 during its broadcast; this would mean that 4.4% of all television-equipped households (that is to say homes with a TV set, not total number of people) were tuned in to that program, while 8% of households that were watching TV at that time were watching the specific program. Because ratings are based on samples, it is possible for shows to get a 0.0 rating, despite having an audience; the

'', which received two 0.0 ratings in the same season. In 2014, Nielsen reported that American viewership of live television (totaling on average four hours and 32 minutes per day) had dropped 12 minutes per day compared to the year before. The CW got another 0.0 rating for its broadcast of the 1st Critics Choice Super Awards. Nielsen reported several reasons for the shift away from live television: increased viewership of time-shifted television (mainly through DVRs) and viewership of internet video (clips from video sharing websites and streams of full-length television shows).


Viewer location: out of home, on the go

In 2007 Nielsen began to release data that reflected out-of-home/not via home TV viewing. This was a follow-up to their added inclusiveness regarding family members who are dorming in college.


Demographics

Since specific demographics influence advertising rates, Nielsen provides statistics by categories including age, gender, race, economic class, and area. For example, an advertiser might look for younger viewers, for older or wealthier audiences, or for women rather than men. In general, the number of viewers within the 18–49 age range is more important than the total number of viewers. According to ''

Commercial ratings

Nielsen also provides viewership data calculated as the average viewership for only the commercial time within the program. These "Commercial Ratings" first became available on May 31, 2007. Additionally, Nielsen provides different "streams" of this data in order to take into consideration delayed viewing (DVR) data, at any interval up to seven days. C3 was the metric launched in 2007, and refers to the ratings for average commercial minutes in live programming plus total playback by digital video recorder up to three days after. In 2009, dissatisfaction with Nielsen's effectiveness resulted in formation of the Council for Innovative Media Measurement by more than six major broadcast media companies. By the end of 2012, some television executives wanted to see C7, ratings for live plus seven days, with

Sweeps

The American television measurement by Nielsen is based on three different methodological approaches. In the 25 TV markets with the highest sales (e.g. New York, Los Angeles, Chicago, Denver), the Local People Meter (LPM) is measured. Individuals register individually; the measurement is carried out on 365 days over 24 hours. The SET Meter (Diary & Electronic) is used in 31 smaller markets (such as Nashville, Salt Lake City). In four sweeps in February, May, July, and November, target group data are collected with the diary and validated with the data of the devices (TV set on/off) in the participating households. In the 154 TV markets with the lowest sales (e. g. Harrisburg, PA or Honolulu) the use of TV is only recorded using a diary survey. Each year until 2018, Nielsen processed approximately two million paper diaries from households across the United States, for November, February, May, and July—also known as the "sweeps" rating periods. The term "sweeps" dates from 1954, when Nielsen collected diaries from households in the

first; from there they would "sweep" west. Seven-day diaries (or eight-day diaries in homes with DVRs) were mailed to homes to keep a tally of what was watched on each television set and by whom. Over the course of a sweeps period, diaries were mailed to a new panel of homes each week. At the end of the month, all of the viewing data from the individual weeks was aggregated. One exception to the normal sweeps periods occurred in 2008–09 when the February sweeps period was moved to March to accommodate the digital television transition, which was scheduled to take place on February 17, 2009. The transition date was later moved to June 12, but Nielsen kept the sweeps period in March that year rather than moving it again. This local viewing information provides a basis for program scheduling and advertising decisions for local television stations, cable systems, and advertisers. Typically, the November, February, and May sweeps are considered more important; nevertheless, the July sweeps can have a local impact regarding personnel. In some mid-size markets, diaries provide viewer information for up to two additional "sweeps" months (October and January).


Criticism of ratings systems

There is some public critique regarding accuracy and potential bias within Nielsen's rating system, including some concerns that the Nielsen ratings system is rapidly becoming outdated because of new technology like

streaming services as preferred or alternative methods for television viewing. In June 2006, however, Nielsen announced a plan to revamp its entire methodology to include all types of media viewing in its sample. Since viewers are aware of being part of the Nielsen sample, it can lead to

in recording and viewing habits. Audience counts gathered by the self-reporting diary methodology are sometimes higher than those gathered by the electronic meters, eliminating any response bias. Another criticism of the measuring system itself is that it fails the most important sample criterion: it is not random. A small fraction of the population is selected, and only those accepted are used as the sample size. In many local areas during the 1990s, the difference between a rating that kept a show on the air and one that would cancel it was so small as to be statistically insignificant. Yet, the show with the higher rating would survive. In addition, the Nielsen ratings encouraged a strong push for demographic measurements. This caused problems with households with multiple television sets or households where viewers would enter the simpler codes (usually their child's), raising serious questions about the demographic data quality. The situation further deteriorated as the popularity of cable television increased the number of viewable networks to the extent that the

has increased because the sampling sizes are too small. Compounding matters is that of the sample data that is collected, advertisers will not pay for time shifted programs (those that are recorded for replay at a different time), rendering the "raw" numbers useless from a statistical point of view. Even in 2013, it was noted that Internet streams of television programs were still not counted because they had either no ads (such as

However, Nielsen countered the campaign by revealing its sample composition counts. According to Nielsen Media Research's sample composition counts, , nationwide,

In 2011, CBS and Nielsen proposed a model consisting of six viewer segments, which according to their empirical research, are more relevant for advertisers than older models based on gender and age. The segments are based on user behavior, motivations, and
