I'm astonished that we've not spotted these caves before. We've had detailed images of the surface for decades.
I can imagine in the future domes being built over these caves to let in light, although getting them sealed and pumped full of air would be a gargantuan task
Unless the set top box (apple or whoever) has an aerial/satellite /Cable input you still need to use the normal TV to watch standard channels, exposing you to the UI adverts.
I had considered buying an Apple TV, but my Samsung TV does everything I want just with stupid adverts, which I won't be able to get away from if I have to swap sources to Apple TV and back to live TV
