It pretty much fizzled out by 2013 when Foxtel axed their 3D channel (just one year after the most recent FTA trial), while 3D television sets ceased production a good 4-5 years ago now.
The only way 3DTV is ever likely to work: If someone can come up with a way to view the pictures in 3D which doesn’t require you to wear tacky glasses and/or give you headaches & eye strains while watching. But even then, it’s unlikely that a skeptical public is ever likely to buy 3D when it’s been sold to consumers as “the way of the future” since at least the Early 1980s for TV and even longer in cinemas.
Besides, 3D only really enhances certain number of content genres: Sport + certain types of movies and special event programming. Shows like Gogglebox, Old Peoples Home for 4 Year Olds and Love On The Spectrum have proven themselves to be high quality productions in 2D high definition. And would we really want to see Peter Overton or Scott Cam in full 3D? 
Surely Digital TV viewership had overtaken analogue TV viewership by 2010?
But yes, not that many would’ve been able to decode the 3DTV channel as far less people had equipment which could decode MPEG4 services back then (compared to now anyway) while even fewer had a 3D television set!
