Ratings are measured in a certain number of households selected to take part in ratings measurements. The households are rotated every few years.
There is no way of measuring ratings on every television set in the country.
You can read more about it at the OzTam website.
From The Australian:
Sevenâs Warburton and Tenâs McGarvey have both told The Australian that they are in favour of the move, with the story claiming it could happen as soon as June. The new measuring system VOZ is scheduled to commence in June. Nine and the ABC declined to comment to The Australian.
tvblackbox.com.auâs Molk is against the move saying that
Which would include his website.
Probably because his networkâs ratings arenât that flash and that it would look embarrassing against Nine.
Easier to defend questionable programming decisions (and believe me when I say thereâs been a fair few of those from the networks in recent times) when the numbers arenât released daily, I suppose.
But i thought that Seven (among with the other networks) are good at spin for the overnight ratings.
When was there any doubt?
Sure but that doesnât mean the reason why a weekly model is being pushed isnât valid considering how overnight ratings now donât paint a full and accurate picture about how many people actually watch a given program. Having said that, Warburtonâs argument that the UK & US have ditched them altogether isnât correct.
It would also include this very website/forum
If weâre being realistic, the overnight ratings probably havenât ever been a full and accurate picture of how many people are watching a given program. When peoplemeters were introduced 30 years ago people were taping stuff off VHS along with watching live TV, today itâs PVRs and streaming.
One thing that probably should be done to keep some level of relevancy to the overnight ratings, if itâs technically possible: Including the viewer numbers of channel livestreams via 7+, 9Now, 10 Play, ABC iView and SBS On Demand, as well as linear TV figures via terrestrial, satellite or cable.
Was thinking the same, how convenient when Nine have been destroying the ratings and Seven (until 3 or so weeks ago) and 10 have been struggling. RE: The Australianâs article on ditching overnights and Warburton and McGarveyâs quotes.
Longer-term we might actually see some stability in the guide - which might help retain an audience
wasnât sure where to post this
Was listening to TV Blackboxâs interview with Sunrise EP Michael Pell.
Pell at one stage during the interview, when talking about ratings, said âwe can really break those numbers down, we can go suburb by suburb if we want toâ.
Was he being serious? Or was it just accidentally said on the run and did he perhaps mean RegionalTAM how they report âsun-marketsâ.
Also, unrelated, itâs a fascinating podcast. Well worth a listen whenever anyone had time, apparently very rare that he does one too 
The ratings are easily divided into regions. But beyond that, trying an analysis based of smaller areas would be likely to be inaccurate due to small sample sizes.
Never seen that before, thank you, is it a new feature for networks/buyers/subscribers?
Melbourne âsouthâ wouldnât be very big though (Frankston and maybe a bit north and east of that and Mâton Pen).
The maps are here:
No, itâs been there for over 12 years
Those maps seem to be drawn up rather interestingly from a Sydney perspective with suburbs as far West as Rookwood, Lidcombe, Berala, Potts Hill, Regents Park and Auburn considered to be part of the âCityâ Statistical Local Area!
Wouldâve thought itâd make sense to put any suburbs West of Centenary Drive (thatâs a road often travelled on for Rookwood Necropolis or Olympic Park, interstaters) in either the âWestâ or âSouth West & Southâ SLAs.
I had seen the maps before, just wasnât aware of ratings breakdowns for regions of metro markets. Odd that we never see them publicly, even in articles or from networks from time to time.
From OzTAM
Weâd like to let you know that from 22nd July, weekly top line Consolidated 7 VOZ market reports will be posted to the VirtualOz.com.au website.
Youâll be able to find them on the website reports page.
VOZ insights will be released as VOZ Total TV reporting becomes established in the market.
We look forward to introducing the industry to the VOZ integrated Total TV database and the new perspective VOZ provides on how Australians consume TV content across all screens.
According to The Australian, VOZ reports will be released first at 9am AEST, followed by the traditional overnight ratings at 10am AEST.
