5MMM (identified on air and in print as Triple M Adelaide) is a radio station broadcasting in Adelaide, Australia. Its target demographic is the 30 - 54 age group. Triple M Adelaide is part of the Austereo Triple M Network and broadcasts on the 104.7 MHz frequency.
Triple M Adelaide used to network the majority of its shows from Sydney and Melbourne but in 2011 is focusing on local content with Peanut Gallery and The Stick Shift being the only currently networked shows other than the AFL football.
5MMM had its origins as an AM radio station, commencing broadcasting as 5KA in 25 March 1927 on the frequency 1200 kHz. In 1943 it was purchased by the Methodist Church and attached to the Central Methodist Mission, largely organised by Rev. Samuel Forsyth. The station changed frequency to 1197 kHz in 1978.
In the early 1980s, 5KA adopted a Country Music format and re-branded itself 12K. The format was short-lived.
On 1 January 1990, 5KA became the first of two commercial AM radio stations in Adelaide to convert to the FM band. The station bid $5.5 million in a priced based allocation process the previous year for the FM licence. 5KA moved to the frequency 104.7 MHz and the AM frequency was relinquished. With the FM conversion, the 5KA call-sign was changed to 5KKA and the station was branded on-air as KAFM. The AM frequency was taken over by volunteer-staffed 5RPH.
In 1993, Hoyts Media which owned the Triple M radio network in the eastern states had bought 5KKA but could not adopt the Triple M call-sign in Adelaide as a community radio station already had the call-sign 5MMM. Hoyts then paid 5MMM for the right to use the Triple M name. The community station 5MMM then converted to 5DDD, and 5KKA was then free to change its call-sign to 5MMM and adopt the Triple M network brand.
Triple M is simulcast on Digital Radio in Adelaide.
Triple M launched High Voltage Radio, a "pop up" Digital Radio station that exclusively plays AC/DC for the duration of the band's 2010 tour of Australia. High Voltage stopped being on air on 15 March 2010.
