How do they.......

Ascertain viewing and listening figures for Radio and TV?

I have often wondered how it works....
Firstly how do they aceheive the figure?
Is it calculated by the number of people listening/watching at the commencement of the show or throughout??

I was told that a % of TVs have a 'tracker' fitted that sends details of what was watched and when. Then they calculate how many people watch from the results.

So you have to agree to join the panel to provide figures?
I have never been asked, has anybody here?

We were asked to fill out a record of what we listened to and when on the radio some months back.
The booklet was collected a week later but I can't remember the name of the company carrying out the survey.

Interesting statement.
"The channel viewed the longest in a clock minute is attributed the viewing of that minute. Viewing at anything other than normal speed (fast forwarding/rewinding live or recorded content) is not reported. "

We rarely watch anything Live these days with Sky Plus.
So this is counted as recorded and thus not measured ?
Even when a program is on live , we record it and start watching 15 minutes into the start , so we can Fast forward the dull adverts.

Do you get paid for taking part in the survey ?
