576-line TV at 50Hz interlaced is very much still alive and is the de
facto broadcast standard across the whole of Europe. Of the 134 UK
channels I can get from Freeview, only about a dozen are HD, and those
are all 1920x1080/50i. Several more channels are available in HD but
only behind payment walls for cable or satellite TV (remember that I
said I get TV via Freeview, that's over the air from Crystal palace
through an aerial on my roof). Only a few of those SD channels are 4:3,
and that's only because the material they show is from before 1990 (some
is still from before 1960). All channels are, or can be, 16x9.
'625' line TV (i.e. 576-line x 720 in digitas) is still very much alive.

Strange feeling to see a depiction of 576 lines TV as still a current

I do not watch netflix or similar internet providers for TV
I am still on terrestrial broadcast TV, and all channels seem to be HDTV
(at least the ones i watch). Indeed, it is 1080i. However it is nice
enough, at least on channels that care about quality (Arte, for
example). Clearly, even the potential of this container is not used to
its maximum in many cases.
Progressive could possibly further improve on that, perhaps together
with some bandwidth gain. However, my old faithful 2008 receiver would
probably not handle it.
Currently my only contact with 625 lines TV is with the old Dr Who
episodes from the sixties that i watch from DVD on an
end-of-the-eighties 4:3 CRT, to be closer to the feeling of the time.
I've seen the switch from the english System A 405 lines system to 625 a
few episodes ago ("The Enemy of the World"), and i am 2 or three
episodes away from the switch to color (third doctor)...That is to say i
am in deep legacy :-)
I would be sad if broadcast TV were to disappear, and the magic of radio
with it, something that does not require the continuity of a material
link between the provider and the end user, which can be damaged by
various events including public works, seismic events, or simply failure
of one the components along the way.
