OK, but we actually did this as a commercial service on analogue TV and
we deliver non picture data on digital TV (satellite and terrestrial)
today, it's just not USENET data.

Apologies for disagreeing, but this is exactly what the modern
Digital TV (ATSC in your case, DVB-T & DVB-S in our case) has a
multiplex of a number of independent data streams that can be data,
video or audio. That is carried end to end.
We do this now with other data -
It'd be trivial for us to display USENET directly to read on your TV
or deliver it to the STB ethernet port

Indeed but that is not a digital TV system.

Standard DTV PVR with an ethernet port are a few hundred dollars.
For the people who would actually receive this the box cost is trivial
they just some software. If you have a USB or PCI DTV rx it is trivial
to do whatever you like with the data.
