10 Bold is an Australian free-to-air digital television multichannel owned by Network 10. It originally launched on 26 March 2009 as One HD with a focus on broadcasting sports-based programming and events, but rebranded to One in April 2011 to more reality, scripted and adventure-based programming aimed at males between the ages of 25 to 54. As of October 2018, the channel now primarily broadcasts dramatic programming aimed towards viewers 40 and older.
