One (stylised as ONE) is an Australian free-to-air digital television multichannel, which was launched by Network Ten on 26 March 2009. The channel initially focused on broadcasting sports-based programming and events, but changed in April 2011 to more reality, scripted and adventure-based programming aimed at males between the ages of 25 to 54. Due to the rebroadcast of Ten HD on 2 March 2016, One was reduced to a standard definition broadcast.
