Well, we reach that time in our program when we perform our rating's formula. For that, let's go to expert number cruncher, Boxster O Ryan.
Eh,Thank you, Chip. Nielsen gather the date from the meters to project the number of homes or viewers watching in the entire population. This is named as impressions, but usually, each cable network has a total number of subscribers possibly watching a program, known as a universe. When we take the number of impressions, and divided by the universe, we'll get the percentage, which is our cable coverage rating.
Now, let's say two different cable networks had 25,000,000 people watching at time. One network had 100,000,000 subscribers, while the other had 50,000,000 subscribers. Putting this in our formula, we get oh oh, the first network delivered 25.0 coverage rating, and the other delivered 50.0 coverage rating. Exactly,because the first network's universe is double than latter. It is also important to remember, that the rating is average minutes statistic. So, let's say the most under 25.0 rating. Then 25% of cable network subscribers who watching during the average minutes to . Oh, and what about commercial minutes, do they counted on the program rating too? ah do they?
Oh, you bet they do, all minutes of the program are average together. But many advertisers are anyone waiting for the commercials, but that we just take that average commercial rating in that program. And we improve the anyone who wants , plus any pay within three days. We call commercial ratings C-3 ratings. The C stands for commercial and the 3 stands for filming within 3 days.
That's you blogged in my mind, what else you got? Cable network ratings can also be represented the US ratings, only now, the US ratings universe includes all TV homes in the country. The number of impression is divided by the number of possible viewers in the entire country. This universe is used all broadcast networks and automatically for comparing one cable network to another.
And that's all .Well this all about our time we have in this week, folks. This's Chips b, and I am....saying go for calculate. |
