Take Triple M for example. From market to market the programming philosophy is the same, some of their major shows are networked. So why do they rate so well in Brisbane and Adelaide and so poorly in Sydney and Melbourne? The Talk Network brand is soaring in Perth, Adelaide and Melbourne but just drifting in Brisbane and Sydney. Meanwhile, the two vegas seem to take turns in being up and down from survey to survey in their respective markets of Sydney and Melbourne.

Other networks such as Today and Nova seem more consistent across the nation. Why is this so? Is it about the programming, the audience, the talent, the local culture or the prevailing competition?

It’s probably some or all of the above, but what degree? And how does it change from market to market? Or karma?

What are the differences between each of Sydney, Melbourne, Brisbane, Adelaide and Perth?
