In the station's call sign ATV0, the AT comes from the company who established it, Austarama Television Pty. Ltd., which was a member company of Ansett Transport Industries Limited, and the V indicates that the channel broadcasts in Victoria, Australia.
The first programme ever broadcast on television station ATV0 in Melbourne, Victoria, Australia.
A special feature on the launch of ATV0 published in Melbourne newspaper The Age on 31 July 1964, the day before its first broadcast, contained messages of best wishes for the new station from several companies. One of these, stating "Congratulations, Best wishes and Success to Austarama Television" came from CBS Television Programs. 53 years later, after ATV0 became part of Network Ten, the network would be acquired by CBS Corporation.
