Triple M is an Australian radio brand owned and operated by Southern Cross Austereo. Under this brand falls four networks – the longest-running and 'main' network is the Metropolitan network – which focuses on a mix of rock, sport and comedy. There are four of these stations all in capital cities. The second is the Digital Radio network, which consists of all the rock, sport and comedy stations – as well as KOFM, Gold FM, Mix 94. 5 & Mix 106. 3 plus 'Triple M Classic Rock', 'Triple M Country', 'Triple M Aussie' and 'Triple M Greatest Hits'. The third network is one part of the former LocalWorks network – the Greatest Hits network. This was formed on 15 December[when?] when most of the stations owned by Southern Cross Austereo were rebranded to either Triple M or Hit. These play the 'Greatest Hits' from the 1970s–present, or the 1980s–present (depending on local audience demographics). Also formed from the end of the LocalWorks network was the Classic Hits network, which plays the 'Classic Hits' of the 1960s, '70s, and '80s.
