Huh?
• Your schedule generates 168.8mm HH GI yet there are only 105.5mm TV HH – How is this possible?
• Your schedule generates 159.7 GRPs, with each GRP equal to 1% of the audience– How can you have more than 100%

Duplication of Impressions
• GRPs and GI allow for the duplication of impressions– Someone might see more than one ad
in your schedule• Ex. Survivor and X-Files• Ex. multiple episodes of X-Files• Ex. multiple ads in a single show

Reach and Frequency
Viewers Average NumberGRPs = Counted X of Times
Once They View
GRPs = Reach X Frequency
Reach is net unduplicated audience
Frequency is average number of exposures

Estimating Reach and Calculating Frequency
• Back to our 10 unit schedule of ads– GRPs = 159.7– Reach = 60.0– Frequency = 2.66 or 2.7
– Numbers comes from “reach curves” that contain reach estimates for various media vehicles and GRP levels
– Frequency is then calculated from reach

Estimating GRPs and Calculating Reach
• Planners don’t always start with GRPs leading to reach estimates– Sometimes they have a desired reach or
frequency in mind and calculate the number of GRPs they need to schedule
– Sometimes they can only afford a certain number of GRPs and use a clear frequency goal to estimate the reach

CPM
• CPM = Cost per thousand impressions• CPM = Cost of ads / Total GIs in (000)
– Ex. CPM for Survivor– CPM = $400,000 / 22,500(000) = $17.78
– Ex. CPM for 10 unit schedule– CPM = $2,450,000 / 168,800(000) = $14.51

CPP
• CPP = Cost per rating point• CPP = Cost of ads / Total GRPs
– Ex. CPP for Survivor– CPP = $400,000 / 21.3 = $18,779.34
– Ex. CPP for 10 unit schedule– CPP = $2,450,000 / 159.7 = $15,341.26

From HH to Demo Groups
• So far, we have focused on households– But strategic communicators are typically interested
in smaller demographic groups
– We need some way to convert household audience numbers to demo group numbers
– This is where VPVH — viewers per 1000 viewing households — is helpful
![Page 11: Media and Estimates of Audience Exposure. Media Schedule Rating Aud. Size # of Ads GRPs GI Survivor 21.3 22.5 mm 3 63.9 67.5 mm Friends 23.9 25.2 mm 2](https://reader036.vdocuments.site/reader036/viewer/2022082817/56649dd05503460f94ac5afe/html5/thumbnails/11.jpg)
VPVH
• Viewers per viewing households– Telescopic look inside the households that
are tuned to a specific program– For every 1000 HH in the US, how many
demo group members are viewers
• Number of viewers / 1000 HH
![Page 12: Media and Estimates of Audience Exposure. Media Schedule Rating Aud. Size # of Ads GRPs GI Survivor 21.3 22.5 mm 3 63.9 67.5 mm Friends 23.9 25.2 mm 2](https://reader036.vdocuments.site/reader036/viewer/2022082817/56649dd05503460f94ac5afe/html5/thumbnails/12.jpg)
VPVH
• Describes audience composition • Ex. For Survivor, W18-49 VPVH = 644
– If we count the W18-49 who watch Survivor, we find that there are 644 for every 1000 Survivor viewing households
– 644 W18-49 / 1000 HH x Total Survivor HHs– 644 W18-49 x 22,500(000) = 14,490,000 W18-49
