9Gem was previously launched on 26 September 2010 as GEM, one day after Seven's multichannel 7mate.
The name change came about as Nine Entertainment Co. sort out to rebrand most of their channels by adding the iconic 9 dots, sharing in the heritage of Australian TV they represent. The new logo features with the 9 dots and the word 'Gem' in a new typeface.
9Gem introduced its colour variations on New Year's Day, 2018. The 2015 logo still remains.
