5AA (identified as FIVEaa, see logo, right), is 50% owned by dmg Radio Australia and Lachlan Murdoch's company Illyra, and is Adelaide's only commercial talkback radio station. The station has a range of programs including news, sports, current affairs, social issues, football calls, gardening, lifestyle, cars, travel and health.
5AA commenced service in Kent Town on 9 March 1976 on the frequency 1390 kHz. It was moved to 1386 kHz with the introduction of 9 kHz spacing on the AM dial in 1978. The station now broadcasts on 1395 kHz.
5AA commenced its life with a "Beautiful Music" format and quickly became Adelaide's no 1 rating radio station. In 1976, the only FM competition was the ABC owned Classic FM. AM stations were the ABC owned 5AN, 5DN 972 - "Licenced to talk" and music stations 5KA on 1197AM and 5AD on 1323AM.
In the 1980s 5AA was sold to the State Government owned TAB, ditching music to begin broadcasting horse and dog racing, with talkback in between race calls. The station shifted to the TAB headquarters in Pulteney Court, Adelaide, with "Talk of the Town" as its slogan. However, it plummeted in popularity as a result of its schizophrenic broadcasting policy. With the advent of narrowcast licences, the TAB purchased frequency 1539AM and shifted all racing there, freeing up 5AA for talk and interviews.
A new slogan was adopted in the early 1990s, "5AA, Where you don't miss a thing" and the station began a slow rise in the ratings to challenge 5AN (now 891ABC) and the rebadged 5DN, on the 1323AM frequency (now Cruise1323).
On 27 September 1996, 5AA was separated from the TAB and sold by the State Liberal Olsen Government as part of its asset sales program to repay state debt, caused by the $3 billion collapse of the State Bank 5 years earlier. The new owner became dmg Radio Australia, under the local Chairmanship of CEO Paul Thompson, with the national headquarters based in Adelaide. (In 1980, Thompson established Double-S-A FM (now SAFM) as the first FM commercial radio station in Adelaide, which led to the formation of radio giant Austereo.)
In 2000, another new logo was adopted with the tag, Interactive Radio FIVEaa and in October 2004, the station shifted to new premises in Hindmarsh Square with the launch of NOVA 91.9 FM, also owned by dmg Radio Australia, two months earlier.
In November 2009 dmg sold 50% of its share to Lachlan Murdoch's company Illyria and Paul Thompson became non-executive Chairman for six months, before retiring from an illustrious radio career spanning 4 decades and an induction to Radio's Hall of Fame.
