ABC News (formerly ABC News 24; also referred to as the ABC News channel) is an Australian 24-hour news channel launched and owned by the Australian Broadcasting Corporation. The channel replaced and used the then-former ABC HD channel space (which simulcast ABC TV in high definition) and commenced broadcasting as ABC News 24 at 7:30 pm (AEST) on Thursday, 22 July 2010. The network is a division of the ABC's News and Current Affairs department. The majority of the channel's content is produced from the studios of the ABC's Sydney station, ABN, in Ultimo, Sydney which the public can view being presented from an atrium looking into the news presentation studio. The ABC's breakfast television programme, News Breakfast, Afternoon Briefing and the evening programme The World is produced at ABV Southbank, Melbourne (weekdays). Due to the relaunch of ABC HD on 6 December 2016, the picture format of the ABC News channel was reduced to standard definition. ()
