minute for a given time period over the length of this period (= L)
...





AMR % = AMA X 100

TGT
• Average Time Spent: ATS is the amount of time that the average individual spent
viewing during the time period
...

SHR % = AMA (channel x) X 100
AMA (total channels)
• Reception Share: The cumulative audience of a channel for a given period (program or
break) as a percentage of the cumulative audience for the total broadcasting time of the
same channel
...

•

RSH%= AMR%OF a break during a program
TVR of the total program

Rating = Target audience
Population
• GRP=sum of rating (TVRS)
Or
GRP=Reach x frequency
• GI: sum of all exposures
n(AUBUC)= n(a)+n(b)+n(c) –n(A∩B) –n(A∩C) –n(B∩C) + n(A∩B∩C)
