Be willing to be that cameras are embedded (if not already) into tv’s so you can be watched.
I know some smart TVs have ‘above the screen’ cameras. Then there is this: “Apple files patent for camera hidden behind display” http://appleinsider.com/articles/09/01/08/apple_files_patent_for_camera_hidden_behind_display
So that’s why I’m using a 25 year old tube TV.
The new "smart" tv's have cameras & microphones already built in.
