They also own 2CH acquired prior to the Fairfax Media merger. With the "2 station rule", 2CH will be sold.
Macquarie Radio Network started with 2GB. It was part of the Macquarie Network which was broken up when Macquarie Broadcasting Holdings sold their stations. In 1994, 2GB was bought by Macquarie Radio Network.
In 2010, Fairfax Media owned the other talk stations including 2UE in Sydney and 3AW in Melbourne. To expand into Melbourne, Macquarie Radio Network started a partnership with Pacific Star Network, the owner of 3MP, to create Melbourne Talk Radio (MTR). The station only lasted two years.
In 2011, Macquarie Radio Network bought Smart Radio Group. The six stations are the Macquarie Regional Radio and operated as a subsidiary network from the metropolitan networks.
In 2015, Fairfax Media merged with Macquarie Radio Network bringing 2GB together with the other talk stations.
