Anyone know what the old classification system was, at least for commercial?
The current one has been in force (tweaked a few times) since the early 2000s I think, with significant visual changes in mid-2000s coinciding with the then OFLCâs overhaul introducing the âcoloursâ.
But I think in the 90s and prior it was âG, PG, M & AOâ? With no âMA15+â? Even though the OFLC introduced that aforementioned rating in early 1993, commercial FTA didnât adopt it at the time. So all MA and R movies had to be edited to M, a heavy censorship period I believe.
Iâll tag @TelevisionAU @TV-Expert @Zampakid who will probably know. 
In the 1970s they had âGâ, âAâ and âAOâ.
âCâ was created in 1979.
In 1981, âAâ became âPGRâ
âPâ for pre-school shows was introduced late 1980s sometime, maybe 1988?
In 1993, âPGRâ became âPGâ, âAOâ became âMâ. I think to align the classifications closer to movies.
âMAâ and âMAVâ came along either at this time, or later. I canât recall.
One of the complaints was Season 1 Episode 1 which was AV15+ on GO! and MA15+ from OFLC.
A clear breach apparently. 
Googled the synopsis and itâs an erotic show for gay people.
Nine argued it wasnât. 
Did Seven edit Seinfeld? I actually never noticed anything.
I realise the CB gave all (?) seasons âMâ, so that would suggest networks made edits even if very subtle/minor.
I only recall a single episode being given âMâ with âSexual Referencesâ by Seven, with virtually every other a âplainâ âPGâ.
I caught up with Mondayâs episode of The Voice finals tonight, and the first thing I saw was that the show was rated M for âthemesâ. The only reason I could think of is the song chosen by Kelly Rowland for Denzel to perform: Power by Kanye West. Nine even showed the phone number for Lifeline after the judges delivered critiques for Denzelâs rendition. This season of The Voice had been rated PG up to this point.
But according to 9Now it shows thatâs an m rated show which was quite unusual. When Nine aired it on TV last Monday, it was a PG classified and contained mild coarse language.
Casino Royal that will be shown in some Nine markets on Saturday is split into 2 parts with the 7pm part rated PG - AV - Action Violence, S1 - Sexual References and part 2 at 8.30 rated M - AV - Action Violence.
The Code states (at the âPG - mild impactâ level):
Suicide: Visual depictions of and verbal references to suicide or attempted suicide must be inexplicit and restrained. It must not be presented as a means of achieving a desired result or as an appropriate response to stress, depression or other problems.
So did Nine think such content in this episode exceeded that?
Nine might have considered some of the lyrics in Power (Now this would be a beautiful death jumping out the window) exceeded the code.
Whatâs the difference between SBS/SBS Viceland/SBS World Movies and NITV/SBS Food? Why canât SBS Food and NITV show M rated programs on weekends/school holidays between 12pm-3pm?
Well I sure canât imagine any of SBSâ cooking shows with a rating of M, can you? 
It was probably easier for SBS to get an exception for only some of its channels instead of all of them.
Maybe if SBS FOOD ever got the rights to some Gordon Ramsay cooking shows? 
Also, doesnât NITV air some childrenâs programming during the day? I could imagine that being a factor as to why the classification rules werenât changed for that channel.
Not sure why the commercials are complaining. I thought the âCommercial Television Industry Code of Practiceâ that includes the classification rules was something that they wrote themselves and them lodged with ACMA. The latest version was only lodged in 2018.
Nine split Casino Royale into two for classification purposes but in the ratings it was coded as a single program. Previously it split Lord of the Rings into two for classification and coded the movie accordingly. So confusing.
Nice to see a topic thatâs been discussed on MS quite a bit also noticed by other media
