MVPDs are losing subs but they're still in a majority of US homes and way more Americans watch local channels via MVPDs than by OTA antennas.
Agreed. But network-connected "gateway" ATSC 3.0 tuners -- similar to HDHomeRun's line of OTA tuners -- could be the answer. Connect your OTA antenna and then connect it to your home network. Optionally plug in a storage device for DVR service. Then all the devices on your home network can access live (and DVR'd) OTA TV. That's the concept that the group behind ATSC 3.0 has been touting for years (in addition, of course, to tuners built into TVs). But if such devices are going to take off with the general public, then it will take a concerted effort on the part of OTA broadcasters to advertise (and maybe even subsidize) them, and perhaps join together to produce a single standard free "NextGen TV" app for all the main platforms (Roku, Fire TV, Apple TV, Android TV, iOS, Android, Samsung TV, LG webOS, Xbox, PlayStation, etc.). It remains to be seen whether that will happen and, even if it does, to what degree US households will bother with it versus just getting the same content via MPVDs and/or streaming apps like Hulu, Paramount+, Peacock, PBS, CW, etc.
