The Australian Newcastle Broadcasting and Television Corporation was officially opened on 4 March 1962. It broadcast on Channel 3. It covered as far north as Bungwahl, as far west as Aberdeen and as far south as Broken Bay. The first news was read by Murray Finlay at 6pm on the first day of transmission. Transmission times in the early years were 3pm to 10.30pm Monday-Saturday and 1pm to 11.30pm Sundays.

It was the first station to introduce a one hour news service in March 1974.

The name was changed to NBN in October 1979.

Before aggregation, NBN had expanded as far north as Forster/Tuncurry, as far west as Muswellbrook and as far south as the Hawsberry River.
