"With the Holy Grail of TV still likely a long way off... "
That's a ridiculous statement. There is no 'Holy Grail' of any technology. Remember one B. Gates saying, probably some years before you were born "I can't see why anyone would want more than 640km of memory" ?
Actually, he never said that. It's a techie urban myth but the principal holds. Tech is an endless belt, as at Tesco checkouts. At some point you have to make a decision and plonk your choice on the belt, pay up and 'consume it' - ie watch TV.
But what someone did say - I am old enough to be of the time when it was said - on the opening of Calder Hall nuke power station, "With a few more like Calder Hall, electricity will be too cheap to meter
". That was a Government Minister! Complain now to your lekky supplier - they said it was gonna be free! The Holy Grail of lekky generation!
May be in days to come, when I care even less about 'Holy Grail' tech, you will be able to paint LEDS or somesuch onto a wall, stick a cable onto it and have a wall of content at better than human optical resolution.
Then they'll offer content direct to your audio-visual cortex. Mad Max XXV
