Remember William Peter Blatty? For those born after the late Cretaceous, he was the author of The Exorcist, the novel from which a movie was made which for some still sets the standard for horror films.
Blatty isn't entirely conventional in his theology. But nobody has ever claimed that he didn't do his research. And he's correctly identified one manifestation of Old Scratch in our contemporary society.
Wherever you stand on demonic possession, that manifestation is truly satanic.
