Last week, Nine Radio celebrated three years since they took over the Macquarie Radio Network from the previous owners headed by John Singleton.

During that time, there’s been significant change in the talent line-ups but also, an overall gain in audience and profitability at 2GB, 3AW, 4BC and 6PR, .
