9Go!

The general concept for GO! was revealed on 23 March 2009, with the Nine Network announcing their intention to start a standard-definition variety-based multichannel, launched midway through 2009. The channel's name and branding was first revealed as GO!99 on 14 April 2009 by TV Tonight, a blog dedicated to Australian television.[5]

The channel's final name was confirmed by the Nine Network via A Current Affair as GO! on 15 July 2009,[6] as well as multi-coloured logo variations.[2][6]

The channel went to air at 1:00 pm on 5 August 2009, broadcasting a promo loop. GO! officially began broadcasting scheduled programming from 9 August 2009 at 6:30 pm with a 1-minute promo featuring the song "Go!" by Sydney based sound house group Noise International featuring vocals by Sharon Muscat.[7][8] It was then followed by an episode of Wipeout, the first programme to air on the new channel.[9]

Darwin received the channel in October 2010 (over a year after other capital cities started transmitting the multi channel). From December 2010, Nine Network affiliate Imparja Television commenced transmission of the GO! channel to viewers in remote areas of Central, Northern and Eastern Australia,[10] before expanding to Eastern South Australia on 11 November 2011.

There have been reports that GO!'s technical launch had caused a significant number of digital TV receivers to no longer pick up Nine's digital channels. In response, Nine established a helpline for viewers experiencing problems or requiring assistance to tune in to the new channel.[11]

On 24 November 2009, the channel launched via Foxtel Cable on channel 129.[12]

After major demands for the channel's theme song (which was written specifically for the channel, going as far as remixes of the 1-minute cut being played in clubs), it was released independently by Noise International on 4 December 2009,[13] having promised a month earlier.[7] A music video was also produced (notable for the usage of neon dancers), which was regularly shown as a filler on the channel.[14]

GO! celebrated its first birthday in 2010 by playing movies every night at 10pm during the month of August 2010. GO! also played a mini clip during the commercial breaks thanking everyone for watching GO!.[15]

In September 2010, GO! aired a promo promoting new shows using the song All Eyes on Me by Sammy Small, licensed from Extreme Music.[16]

GO! introduced Newsbursts, a news-break filler program in 2010. Presented by Sophie Walsh, these would usually feature a few breaking news stories and the weather. These were later dropped in 2011, replaced by repeats of Nine Newsbreak.[17]

GO! received a new on-air presentation for 2011. GO! also played a mini clip after programs during Summer 2010/2011, featuring the song "Hello" by The Potbelleez, using the slogan "Let's GO! 2011" to promote new shows airing on the channel.[18] This presentation remained (mostly) unchanged for the next few years.

On 26 November 2015, the Nine Network introduced a network-wide rebrand of all of its digital channels with GO! being renamed 9Go!.[19] Additionally, 9Go! was moved to channel 93, but a simulcast currently remains available on channel 99.[20] Later, 9Go!'s on-air theme was changed for a continuous design across all of its channels. This included a new look for program listings, program advertisements and promos and introduced the in program classifications.

Nine announced that it had signed a new affiliation deal with Southern Cross Austereo on 29 April 2016, replacing WIN Television as the primary Nine affiliate starting 1 July 2016.[21] Consequently, 9Go! was broadcast by Southern Cross into Regional Queensland, Southern NSW/ACT and Regional Victoria on channel 53, also on TDT in Tasmania on channel 53.[22][23]

On 12 December 2016, 9Go!'s daytime schedule was mostly reformatted into a children's programming block branded Go! Kids.[24] Children's programming aired from 6am to 6pm on 9Go! in addition to being available via streaming on the 9Now service, with regular programming broadcast outside of those hours.[25] In late 2019, the Go! Kids block was no longer in this network because the cancellation of Kids' WB and their long-running output deal with Warner Bros, but remained online instead.

Nine announced that WIN Television has returned as the primary Nine regional affiliate from 2021. Consequently 9Go! got bumped up to channel 82.
