Thanks for that; I didnât know who ripped off who. It does not surprise me to learn that an Australian station copied the Kiwi one.
Radio i/i 98FM in Auckland definitely used it first. They converted from 1332AM to 91.8FM in March 1990 but failed to secure that frequency long term when it was put up for tender six months later. However, in August 1990 they successfully tendered 98.2FM and started using this logo:

In 1991, they dropped the word âradioâ from their name and modified their logo to this one:

Great stuff. Bogart Torelli of course, is on Smooth 95.3 breakfast nowadays alongside then-WSFM breakfast newsreader Glenn Daniel.
Juliette Saly is currently a Singapore-based presenter on Bloomberg Television, but was one of the youngest breakfast newsreaders on Sydney radio back in 2002 when she was reading Mix 106.5âs bulletins. Moved to Drive for the first few months 2003 before leaving ARN to travel overseas.
Imaging voiceover wise weâve got Abbe Holmes (who also did the Mix 106.5 TVCs in 2001/02), Paul Pittioni (at the start of that âMitsubishi Challengersâ Promo, probably the voice most associated with Mix FM) plus another male VO who sounds familiar but I canât pick the exact name of!
And advertisement for 5AAâs AFL coverage around 1993 judging by the grounds shown here.
From TRV:
This aircheck was recorded on 2nd April 1989, exactly one year after 3TT had launched, replacing 3DB.
3TT ⌠part of the then mighty Albert family commonwealth broadcasting company group of radio stations. Headed by the superb flagship 2UW Sydney of course. 4BC also plus a clutch of regionals. A mighty network through the 60s to 90s.
I remembered 4RO in Rockhampton had a very similar format and jingle to 3TT back in the late 80âsâŚYes I am showing my age 
I remember that too as 4RO used to boom into New Zealand at night. There were no Kiwi stations on 990kHz back then.
Yes it sounded familiar to me too, so Iâm thinking maybe 4MB also had something very similar at that time? I think 4RO and 4MB were still under the same ownership then.
I think are right there mate. I also remembered 4GR sounded similar also.
From memory 4RO and 4CC did distant themselves. 4RO had the âClassic Hitâ format, while 4CC had a âHot Hitsâ type format.
3TT was a fairly late addition to the network, only joining when 3DB got taken over in 1987 and the new owners changed the call-sign.
When/how did the group come to adopt the Australian Radio Network or ARN name that we know now?
Yep at one time in the 80s 4RO, 4MB and 4GR were under the same ownership or at least control. And yes 4CC was a more AC type of station leaning towards CHR by the end of the 80s.
4CC was very similar to 4GY in the second half of the 80s as both were owned by Wesgo. At that time many younger listeners in Maryborough like myself tuned to 4GY. Just as in Rockhampton most younger listeners would have been tuned to 4CC.
Yes, us youngsters used to always listen to 4CC while my parents liked 4RO.
Before I moved to NSW, 4CC went very CHR.
This article from 1988 sheds some light : RADIO TURBULENCE, BUT ALBERTS RULE THE WAVES
What was for many decades known as the Commonwealth Broadcasting Compnany morphed into the Australian Broadcasting Company still fully owned by the Albert family. Then from Feb 1988 the business became the Australian Radio Network as it pushed out into distribution of programming and news across 27 stations (2nd largest network after Macquarie).
Just to finish off ⌠Alberts sold their radio interests in 1995 to APN (Australian Provincial Newspapers). APN later entered a joint venture with US company Clear Channel (later renamed iHeartMedia) for the radio business in Australia. In 2014 APN bought out Clear Channel and the business owner of ARN is now known as Here, There & Everywhere (HT&E).

This sounds about right.
In 2014 APN bought out Clear Channel
Actually, APN News & Media (as they were still known as back then) purchased Clear Channelâs 50% stake in the Australian Radio Network - this lead to the radio broadcaster becoming an entirely APN/HT&E-owned entity. Although ARN still has the rights to operate the Australian version of iHeartRadio, likely as part of a long-term agreement with iHeartMedia.
APN also used to have significant radio/publishing interests in New Zealand, but those too have since been spun off into NZME and separated from the businesses in Australia.
the business owner of ARN is now known as Here, There & Everywhere (HT&E)
This name change happened in May 2017, following the 2016 sale of Australian Regional Media (the regional papers) to News Corp.
likely as part of a long-term agreement
Exactly how it works.
