• Media : Carriers and deliverers of advertisements.
• Medium : A broad general category of carriers
• Vehicle : A specific carrier within a medium

16. Plan Reach
“Percentage of our target universe that was exposed at least
once to an advertising schedule.”
Usually measured over 1 or 4 week period
Hence, in the previous example,
Target Universe = 10
A campaign achieves 90% reach, which means that 90% of
the target (i.e. 9 out of 10 TA) have seen the commercial at least
once
17. Reach Caveats
• As insertions are added to the media schedule, only the
audience not previously exposed to the message are added to
the reach total.
• Thus, once a person is counted in the reach, that person is not
counted again no matter how many times the person is
exposed.
• Reach can never be greater than 100%.
18. Average Frequency
“The number of times, on average, the audience reached sees the
commercial during a given period. ”
Again, in the previous example,
Average Frequency of 1.8 means that, as an average, every
person reached has seen the commercial 1.8 times. This is an
average, which means that some people will have seen the
commercial more times, and some less. The average gives us a
general idea of the campaign frequency performance.
19. Gross Rating Points (GRP’s)
“The sum of all ratings achieved in a given period.”
20. • GRPs or TRPs are results of the reach and frequency goals we
set
• GRPs or TRPs are not goals by themselves
• GRPs or TRPs alone don’t tell us what we really achieve

22. Rules
• Never add GRPs/TRPs that belong to different target definitions (will have to use weighted
averages)
• Never add GRPs/TRPs that belong to different markets (will have to use weighted averages)
• GRP’s can be added by brands, by durations and by weeks/months.(as long as TA and markets
are identical)
• GRPs /TRPs can be calculated adding the ratings of the advertising campaign spots
• Reach and Average Frequency can only be calculated with computer software
• Reach can never be higher than 100
GRPs / TRPs , Reach & Frequency
23. Same GRP levels Reach Freq.
• Increasing day parts
• Buying same kind of programming, usually
• Increasing # TV channels/publication
• Buying only 3 days of the week

GRPs / TRPs, Reach & Frequency
24. Cost Per Rating Point (CPRP)
“Cost of reaching 1% of my target with a specific medium.”
Formula :
Medium or Vehichle Total Cost ÷ GRPs or Rating = CPRP
In the previous example, assuming it costs Rs 3,00,000/ to
buy those 3 spots (= 160 GRP’s)
CPRP = 300000/160
= 1875.
25. Cost Per Thousand (CPT)
“The cost of reaching 1000 individuals within my target
with a given medium or specific vehicle”
Formula :
Medium or Vehicle Total Cost ÷ Target Audience (in 000’s) = CPT
41. Frequency Distribution
• Average Frequency represents the average number of times the target
was exposed to a commercial message
• But, we know that people are exposed at different rates. Some will see
1 message, some 2 messages, some 4, and some may even see all of
them
Frequency Distribution describes the number or
percent of population exposed at each
frequency level
42. Frequency % Reached
0 31.7
1 22.3
2 15.4
3 10.5
4 7.1
5 4.7
6 3.1
7 2.0
8 1.3
9 0.8
10+ 1.2
Thus,
32% were not exposed at all
68% saw at least one message
22.3% saw one and only one message
15.4% saw two and only two & so on
1.2% saw 10 or more messages

44. Effective Frequency
“The number of potential commercial exposures
necessary” to communicate the advertising message
effectively
Generally expressed in terms of 2+, 3+, 4+, etc.

48. Forecast future trends
• Normally, we plan for the future using past data. Hence there
is a time lag of almost 2 months between planning and
implementation
• Idea is to simulate the future TV viewing behavior using old
data.
• One of the most important function of a planner is to predict –
– Trends in channels/programs deliveries
– Trends in daypart performance
Always apply 4/6 week averages for planning.
Apply 8-12 wks averages, in case of aberration
49. Optimise cost per reach point
• Three planning variables (R, F and GRP) are
interdependent
– Hence, objective should be to MINIMISE GRP’s(and
thus cost) for given Reach/Frequency
– OR, MAXIMISE REACH for given GRP (cost)
• Objective must be to minimize Cost per reach point and
not minimizing CPRP
51. Must reflect TG viewership behavior
• Since we are operating in one TV HH scenario, data reflects
similar viewership pattern across different TG’s.
• There is a need to identify particular characteristics of target
group and their involvement levels.
52. Know your benchmarks
• It is good to know GRP and R/F benchmarks for your
TG/brand
• Also, know CPRP benchmarks for your TG/brand..
