I was just reading how ATSC 3 (over the air TV) is kind of stalling because they added DRM fairly late in the roll out. Several people bought receivers that are now incompatible.

Also, I'm not sure what the actual numbers are, but my impression is that a significant portion of OTA enthusiasts are feeding their OTA signals into a network connected tuner (HDHomeRun, Tablo, AirTV, etc.) and DRM kills all of these.

DRM being forced into freeview TV seems like a contradiction in terms, and yet here we are.
