Sorry about the double post, but this one’s worth responding to…
I believe that National Nine News started to use that “stripy globe” motif sometime in the mid-1980s. Possibly in 1985 (in Sydney at least) but I haven’t seen enough footage from that era to confirm for sure. By the time it was taken out of circulation in 2006, it had been part of Nine’s news branding for about two decades (although gradually tweaked over time, mainly with changing colour schemes).
Then in 2006, we were introduced to the now infamous “flying billboard logo” which lasted until 2008 when Nine News dropped the “National” from it’s name. During the 2008-09 era we had the rotating rings, spinning earth globes were introduced back into the branding for the Late 2009 graphics change and the “dotted globe” we have now has been the centrepiece of Nine News’ branding since 2012.
