[3][4][5] 2SM's programs are heard across the 2SM Super Radio Network in regional New South Wales, the Northern Territory and Queensland, consisting of over 60 AM and FM stations.

[6] James Meany, a parish priest at St Mark's Drummoyne, raised funds to allow Archbishop Michael Kelly to form the Catholic Broadcasting Co. Ltd, and it obtained a licence for radio 2SM in 1931.

At the time, the station was run by General Manager Bill Stephenson, who started his radio career at 2UE in the 1940s before moving to 2SM in the 1950s.

It had Australia's first team of disc jockeys, dubbed "The Good Guys"—a US-radio inspired format subsequently copied by 3AK, 5KA, 6PR and others.

[6] Then in early 1967 2SM became the first station in the country to adopt the new "talkback" technology which enabled presenters for the first time to broadcast phone conversations with members of the public.

Rod Muir successfully transplanted the American "More Music" format to Sydney, making minor adaptations for the Australian market.

First and foremost, it brought to an abrupt end the days of the true "personality" DJs, as exemplified by 2UW's Ward "Pally" Austin and 3XY's legendary Stan "The Man" Rofe.

It epitomised and defined commercial AM Top 40 radio practice around the country for fifteen years and long after 2SM itself lost popularity, its successful programming formula was still influencing its FM band successors.

[12] With the station still last place in the ratings, it went back to easy listening in May 1994, adopting the new name Gold 1269 and by Survey 8 1994 hit the heights of 7.1%.
