2SM is an Australian radio station, licensed to and serving Sydney, broadcasting on 1269 kilohertz on the AM band. It is owned and operated by Broadcast Operations Group. The SM call sign is taken from the initials of Saint Mary's. 2SM's programs are heard across the 2SM Super Radio Network in regional New South Wales and Queensland, consisting of 32 AM and FM stations. 2SM unveiled its renowned denim zipper logo in 1975. Although the logo is inextricably linked to 2SM, it was, according to radio historian Wayne Mac, actually created for Brisbane pop station 4IP by a company called Eagle Marketing and subsequently adopted by other stations including 2SM, 3XY and 2NX. History James Meany, a parish priest at St Mark's Drummoyne, raised the finances to allow Archbishop Michael Kelly to form the Catholic Broadcasting Co. Ltd, which obtained a licence for radio 2SM in 1931. The station was opened by Archbishop Michael Kelly on 24 December 1931, owned by the Roman Catholic Church. Religious programming was, for most part, not its focus (except for the regular Question Box program of Dr Rumble) but not surprisingly, for most of its life 2SM followed a conservative line in its programming and was promoted as "The Family Station". In 1958 2SM moved to premises at 257 Clarence Street, Sydney but for the next five years it maintained its conservative family-oriented style. 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. In September 1963 Stephenson oversaw a radical overhaul of 2SM's format when the station finally commenced 24-hour service. In those days it was still common for radio and TV stations to close in the late evening and, as many readers will recall, this practice persisted in commercial television well into the 1970s. 2SM was relaunched as a Top 40 station, featuring Australia's first team of disc jockeys, dubbed "The Good Guys"—a US radio inspired format subsequently copied by 3AK, 5KA, 6PR and others. This set the trend for years to come, with 2SM relying heavily on adapting of formulaic programming strategies sourced from American commercial radio, which in turn were then picked up by other stations around the country. Searching for an alternative, in early 1967 2SM became the first station in the country to adopt the new "talkback" technology which
