This is a commonly misattributed quote: it was not written by Orwell, but by the two authors who adapted 1984 into a play in 2014, long after cell phones were invented (and after “cell phone bad” hysteria started).
(It’s also dumb as shit because the whole thing with 1984 was that looking at the screens during news broadcasts was mandatory and the screens were watching you – the concept of a dystopia brought about by pacifying the masses with entertainment is a Brave New World thing, not a 1984 thing)
