In those days, there were a variety of owners across a number of the above stations.
In around 1996:
Sun FM/3SR - Goulburn Valley Broadcasters (A.E. Fairley)
Classic Rock 102.5/2QN - Rich Rivers Radio (Robertson Family)
3BO FM/3CV - Broadcast Media Group

In late 1996, Broadcast Media Group were bought out by DMG. By the late 90s, RG Capital bought Sun FM/3SR, initially in a JV with Goulburn Valley Broadcasters before owning them outright by the early 2000s. Rich Rivers Radio merged with North East Broadcasters (3NE/Edge) in 2002.
3SR moved from AM to FM into a new licence in October 1998, whilst 91.9 Star FM in Bendigo launched in October 1999, which was basically 3CV moving to FM, with Easy Listening 1071 launching on 3CV’s former AM licence under a new callsign of 3EL.
Today, around 25 years later, the same above stations are owned as follows:
Edge FM/2QN - ACE Radio
Hit 91.9/93.5 Triple M/95.3 Triple M/Hit 96.9 - SCA
Gold Central Victoria (the former 3CV AM licence) - Grant Broadcasters
Hit & Triple M across both Bendigo & Shepparton now carry the same playlists, a stark contrast to how it was when the same Bendigo & Shepparton stations were owned separately from one another. It certainly makes radio listening in Northern Victoria & South-Western NSW less interesting compared to what it used to be, as other posters mentioned above.
