Broadcast TV seems laughably irrelevant. It’s difficult to find official numbers, but under 1% of US households have no cable, satellite TV, home Internet, or a cell phone. The latter two are how people consume video and TV to a large degree today. In exchange, we have a great deal of spectrum tied up for terrestrial TV, much of which goes to running infomercials or else is surreptitiously leased for terrestrial data…
It's not that people are literally watching these on over the air digital TV antenna systems, but that if you have a "Broadcast TV" station in a certain market, it becomes carried by default on cable systems, direct to home satellite satellite dish systems, and regional FTTH providers' last-mile cable-tv-equivalent products.
Look at for example how all the Seattle TV stations are carried on Comcast or Astound's networks.
