I'm not 100% sure but I think that early TVs had an upward facing CRT showing the picture in reverse and a mirror in the open lid displaying everything the right way round.
It might have been a somewhat more sophisticated method, ie using optics of one sort or another, but you get the drift.
Early CRTs were very long devices and would have been difficult to accommodate horizontally.
