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.
Due to the relaunch of 10 HD on 2 March 2016, it was reduced to a standard-definition broadcast for 5 years until 23 September 2021 at 6am when it switched to HD.
The channel commenced broadcasting as One HD on 26 March 2009 at 7.00 pm in Melbourne (due to live coverage of the Australian Football League) and at 7.30 pm in Sydney, Brisbane, Adelaide and Perth. The channel, owned by Network Ten, featured nonstop sport content including live sport, sports documentaries and sports-themed movies.
One initially broadcast in high definition on digital channels 1 and 11 with a standard-definition simulcast on digital channel 12 known as One SD or One Digital. At launch, One replaced the previous Ten HD service and a standard-definition simulcast of Ten HD called TenSD2.
One HD began broadcasting on Macquarie Media Group's owned and operated Southern Cross Ten regional television stations on digital channel 50 at 7.00 pm on 2 July 2009. Tasmania didn't broadcast it until 30 July 2009, and Mildura didn't broadcast it until 1 December 2009.
The simulcast on digital channel 11 was later reallocated for Ten's standard-definition digital multichannel Eleven (now 10 Peach) on 15 December 2010 in preparation for its launch on 11 January 2011. As a result, the channel's high definition simulcast was moved to channel 12, replacing the standard-definition simulcast.
In 2011, the channel began to dilute its all-sport format to include adventure-themed reality programming such as Ice Road Truckers and Black Gold, and a weekly feature-length movie or documentary, usually, but not limited to, a sporting theme. In April 2011, it was revealed that the channel would shift to a more broad general entertainment channel aimed towards a younger male demographic, whilst still featuring sports programming.
It was confirmed on 4 April 2011 that due to unsupportable overheads associated with running the station as an "all-sport" channel, One HD would begin to air more general entertainment programming alongside sport, particularly shows aimed at an older male audience and would also be rebranded as One. The changes were intended to make the channel a greater competitor against 7mate, which has a similar scope, and took place on 7 May 2011.
One's updated schedule included factuals such as Everest: Beyond the Limit, Extreme Fishing with Robson Green, Airline, Long Way Round, Ice Road Truckers, An Idiot Abroad, Cops, dramas such as Terriers, Lights Out, Sons of Anarchy, Burn Notice, Breakout Kings and Psych and films such as The Last King of Scotland, 28 Weeks Later, Babylon AD, Jarhead, Pitch Black, Doom, Hitman, The Manchurian Candidate and Walker Texas Ranger.
On 31 October 2018, One relaunched as 10 Boss, as part of a larger rebranding of Network Ten. Chief content officer Beverley McGarvey described "Boss" as reflecting an overall "attitude" in its programming, exemplified by a focus on characters with "bold" personalities or could be reasonably described as being a "boss" (such as Judge Judy). 10 Boss primarily targets viewers over the age of 40, and focuses primarily on dramas (such as Madam Secretary and NCIS).
On 10 December 2018, the channel was renamed 10 Bold, due to trademark conflicts with Fairfax Media (which had completed its merger with Nine Entertainment Co.) and the Australian Financial Review publication Boss. A press release promoting the rebranding acknowledged the conflict, describing the change as being an "early Christmas present to Nine", and quipping that "it's better to be bold than bossy".
The channel targets a broad range of viewers, broadcasting programs from Australia, New Zealand, the United Kingdom, Canada, and the United States, and complementing existing programming on Ten. Programs aired on the channel are scripted and adventure-based programming aimed at males between the ages of 25 to 54, mix of genres, including reality, lifestyle, drama, classic sitcoms from the 60s, 70s and 80s, comedies, live sport and action films.
As a result of the revival of 10 HD on 2 March 2016, the channel was reduced to standard definition.
On 17 March 2009, Australian Swimming Championships was broadcast on 10 HD before the launch of 10 Bold on 26 March 2009 showing Live in 2009 until 2015.
In 2010, Both 10 & 10 Bold secured the rights for both Delhi 2010 & Glasgow 2014 also shared with Foxtel only 2010.
In October 2011, it was confirmed that the National Basketball League games would be delayed. During the 2012–13 season, some Friday night games were shown live on 10 Bold at 9.30 pm. Live Sunday games returned to 10 at 2pm.
By March 2012, sport was very much a secondary focus of 10 Bold. Sport is only shown when it clashes with 10's regular programming or as HD simulcast when it airs on 10. Moto GP races airs only on 10 Bold except for the Australian GP round which airs on 10 as well as 10 Bold as HD simulcast. F1 qualifying is shown on 10 Bold live while 10 replays later on.
10 Bold broadcast Formula One Grand Prix every qualifying session shown live with a half-hour preview. Rights to be held till 2014, including IPTV rights from 2011 to 2014 and in 2015 onwards Formula One shows a 1-hour highlight package at 9.30pm Mondays on One that aren't live on Network Ten while continuing with a simulcast on tenplay.
10 Bold broadcast Moto GP every race live (qualifying in highlights only from 2014 onwards) from 2010 till 2014, then from 2015 to 2016. Moto2 and Moto3 and MotoGP will be shown on the Australian Motorcycle Grand Prix round only on Ten.
10 Bold had previously showed NASCAR, between 2010 and 2014 airing both Sprint Cup and Nationwide Series highlights. Every NASCAR Sprint Cup race was shown live between 2011 and 2014.
10 Bold shows highlights for every round of Super Rugby every Sunday morning and replays of every Wallabies Test at around midday, that was previously shown on TEN from The Rugby Championship and Spring Tour
