From Wikipedia: In December 2009, existing operator Pacific Star Network and Macquarie Radio Network, the owner of top rating Sydney talkback radio station 2GB, agreed to create the joint-venture "Melbourne Radio Operations Pty Ltd", to supply radio programming in the Melbourne market. In April 2010, the two signed an interim agreement to launch conservative talkback station MTR 1377—replacing 3MP on AM radio—to compete against incumbent 3AW.
This was the first half hour.
