テレスクリーン

Also known as Telescreens

A telescreen is a two-way video device that appears in George Orwell's dystopian novel Nineteen Eighty-Four. It is a medium that dominates the fictional totalitarian society of Oceania, being present in public and private spaces. Omnipresent and almost never turned off, it is an unavoidable source of propaganda and tool of surveillance used by the ruling Party to manipulate and control the Oceanian population.
