Trojan video?

I think that movies and tv have trained us en masse in a kind of meditation, have made us proficient at letting go of ourselves for extended periods, at putting ourselves into an open and receptive state. Unlike the expansive void produced by traditional forms of meditation, though, this altered state induced by subsuming our ego to the simulacra of life on screens not only opens a gate into our psyches but then uses that channel to program, and often to pollute, our very being. How vulnerable might we be with our defenses thus bypassed by the broadcast?
