In the 80's, Triple M was one of the highest-rating radio stations in Sydney, spearheaded by its breakfast show presented by Doug Mulray and featuring the writing of and occasional appearances by Andrew Denton.

From 1988 until the early nineties, Club Veg with Mal Lees and Vic Davies hosted the Night show before moving to Perth to host the breakfast show at 96FM/Triple M. For all of this period and into the 1990s, Triple M's promotional campaign featured the character "Dr Dan", a guitar-playing satyr with wings, and a theme song that was an extended reworking of the Mike Batt track "Introduction (The Journey of a Fool)", from his 1979 album Tarot Suite.

It was not until the late 1990s when Andrew Denton, a previous contributor to Mulray's program took the chair and became the host of Triple M's breakfast slot, with Amanda Keller joining him as a co-host, that 2MMM once again enjoyed ratings success.

Club Veg with Mal Lees and Vic Davies also returned in 1998 and enjoyed instant ratings success in their morning slot of 9:00am–12:00pm before being moved to the Drive shift 4:00pm–7:00pm.

Andrew Denton left the M's in the early 2000s, and many breakfast teams were tried out, with the likes of Peter Berner, Mikey Robins, and a return of Amanda Keller also during this period.

This went on in Sydney until the end of 2006, with the popular drive show The Shebang taking up the breakfast slot in 2007, to a low degree of success.

In 2007, night show host Paul Murray was added to the Shebang breakfast team in the hope of increasing ratings, to no avail.

Morning DJ Anthony Maroon (who moved to Vega 95.3) was removed from the on-air DJs, along with Rob Duckworth who was in the afternoon slot.

Artists which feature prominently on Triple M include Nickelback, Powderfinger, Kevin Rudolf, Silverchair, Coldplay, The Fray, Snow Patrol, Kings of Leon, Faker, AC/DC, Cold Chisel and Bon Jovi amongst others.

During June 2009, Phil O'Neil and Sami Lukis had been axed from the breakfast slot just over six months since they started broadcasting in December 2008.

As of 17 August 2009, Gus Worland, Stuart MacGill and Mark Geyer were named the hosts of the new Triple M's breakfast show called The Grill Team.

Byron Cooke left The Grill Team at the end of 2010 and moved to the Today Network to anchor Fifi and Jules.
