Demographics

The demographic of a particular show's audience is also measured. This is often notated in an abbreviated form, e.g.:
  • P2+ = Persons aged 2 or more
  • P12-34 = Persons aged 12 to 34
  • P18-49 = Persons aged 18 to 49
  • A18-34 = Adults aged 18 to 34
  • Men 18-34
  • Women 18-34

Ratings point

Ratings point is a measure of viewership of a particular television programme.

 ratings point (Rtg or TVR) represents 1% of viewers in the surveyed area in a given minute. As of 2004, there are an estimated 109.6 million television households in the United States
United States
The United States of America is a federal constitutional republic comprising fifty states and a federal district...

. Thus, a single national household ratings point represents 1%, or 1,096,000 households for the 2004-05 season. When used for the broadcast of a program, the average rating across the duration of the show is typically given. Ratings points are often used for specific demographics rather than just households. For example a ratings point among the key 18-49 year olds demographic is equivalent to 1% of all 18-49 year olds in the country.

A Rtg / TVR is different from a share point in that it is the percentage of all possible viewers, while a share point is 1% of all viewers watching television at the time. Hence the share of a broadcast is often significantly higher than the rating, especially at times when overall TV viewing is low. A low TRP can have an adversse effect on a TV program eventually leading to its closure.

GRPs / TRPs

Gross Rating Points (GRP
Gross Rating Point
Gross rating point is a term used in advertising to measure the size of an audience reached by a specific media vehicle or schedule. It is the product of the percentage of the target audience reached by an advertisement, times the frequency they see it in a given campaign...

s) or Target Rating Point
Target Rating Point
-Definition:Television rating points, or TRPs, are an audience measurement criterion that indicates the popularity of a television channel or programme...

s (TRPs) are chiefly used to measure the performance of TV-based advertising campaigns, and are the sum of the TVRs of each commercial spot within the campaign. An ad campaign might require a certain number of GRPs among a particular demographic across the duration of the campaign. The GRP of a campaign is equal to the percentage of people who saw, multiplied by the average number of spots that these viewers saw. Targeted Rating Points are a refinement of GRPs to express the reach time frequency of only the most likely prospects. For example, if a campaign buys 150 GRPs for a television spot, but only half of that audience is actually in the market for the campaign's product, then the TRP would be stated as 75 to calculate the net effective buy http://forum.researchinfo.com/showthread.php?t=1217.

GRP stands for Gross Rating Point. A standard measure in advertising, it measures adverising impact. It is a percent of the target market reached multiplied by the exposure frequency. Thus, a program which advertises to 30% of the target market and gives them 4 exposures, will have 120 GRP.

GRPs as a measure has some limitations. People like to think of it as a measure of impact, but that is really overstated. Impact should measure sales; this measures exposures, which is in fact assumed not actual exposures.
  • Basics of TAM (Television Advertising Measurement):


Universe: Universe is the total or actual number of people in a defined target audience.

Reach: Reach is the number of individuals from the universe who are exposed to the medium or vehicle.

Reach is normally expressed in terms of % (percentages)
  • Calculation of Reach:


If universe is: 1000000 Individuals (it’s approx. data, it’s usually defined through sampling through people-meter)

For a single episode of a program (30 minutes or 1 hour)
If out of above 1000000 of individuals 600000 saw at least 1 minute of programme then:

Reach = (600000/1000000) x 100

Reach = 60%

Variations of the REACH CONCEPT
  • Gross Reach:


Gross Reach is the summation of all audiences who have been exposed to the vehicle.
  • Week 1: 1000
  • Week 2: 2000
  • Week 3: 1500
  • Week 4: 1200
  • Hence, Gross Reach = week 1 + Week 2 + Week 3 + Week 4
  • Gross Reach = 5700

  • Cumulative Reach


Cumulative Reach: The audiences accumulate over the time
  • The number of individuals within the TG who are exposed to the medium or vehicle over a certain period of time
  • Total time= Total average minutes (universe) x Universe
  • Total Time/ Reach = Avg minutes viewers
  • Net Reach


Net Reach: Net Reach is the summation of all audiences who have been exposed to the vehicle and excludes the duplication of the viewership.
Weeks Gross Reach Total Reach Duplication Total Duplication Net Reach
Week 1 1000 1000
-- 1000
Week 2 2000 3000 (300) (300) 2700
Week 3 1500 4500 (900) (1200) 3300
Week 4 1200 5700 (1000 (2200) 3500

  • What is a TVR (Television Rating Point):

TVR = Reach x Time spent

TVR = (minutes viewed/minutes available) + (mins viewed / minutes available)/N X100

N= Number of individuals
  • Gross Rating Points (GRPs)

The sum of all ratings achieved in a campaign
GRP levels are generally measured and reported on a 4 week basis
It is a measure of the media plan’s trust
  • CPRP

Measurement used in planning a television media buy based on the cost of a commercial time slot and the rating of the program where the time slot is positioned. If, for example, the cost of a commercial time slot during prime time was $1000 and the program rating for that time was 10 (which means that 10% of the total potential audience was tuned to that program), then the cost per GRP would be $1000 divided by 10%, or $100. The CPGRP measurement is a way of measuring the efficiency of media cost, as compared to measuring the cost per thousand (CPT) and is generally used when making comparisons of the various broadcast vehicles. When the actual buy is made, the advertiser will still want to know the cost of reaching people on a cost-per-thousand basis.
Programme Name Time Secondages Effective Rate Total Amt TVR GRP
A 10:00am - 11:00am 150 6000 90000 5.4 81
B 21:00 - 22:00 200 30000 600000 9.8 196
Total - 350 - 690000 - 277

CPRP = 2491 (i.e.,Total Amt/Total GRPs)

 or two.

The process of surveying listeners for their preferences has also been criticised for its lack of flexibility. Listeners complain that modern radio lacks variety and depth but the measurement methods only facilitate further refinement of already minutely programmed formats rather than the overhaul that many listeners are asking for. Radio in the USA, is where listeners hear their old favorites rather than are exposed to new music. Data obtained by some audience measurement methods is detailed to individual songs and how they are reacted to by each age, racial, and economic group the station is seeking to attract. This statistical approach leads to highly recognizable songs (such as those from the Beatles
The Beatles
