Yes, but almost nobody is watching ANYTHING on a native 1080i display

but mostly have disappeared from the market these days. I don't miss
mine at all.
Yes, the notion of interlaced displays was already dying by the time
the ATSC standard hit the air. As Tom knows all too well, this did
not stop stations from investing in a 1080i infrastructure, including
playout, master control, encoders, and other gear specific to 1080i
operations.
NTSC is now gone, and with it the need for fractional frame rates to
deal with interference with the color subcarrier - AKA 59.94. I have
not seen ANY BROADCASTER move to 24/60 FPS, or even heard a wisper
that its time to leave that legacy behind.
Perhaps if broadcasters demonstrated some inclination to "get in
sync" with current technical realities they might be taken more
seriously. Alas, their actions suggest that they are only interested
in riding this ship down as long as it is still profitable, which in
turn helps those who argue it is time to recover some of the spectrum
they are misusing.
