‘Blasphemy and media’ studies how blasphemy has been profoundly changed by media revolutions: first, print, woodcuts, pamphlets, and newspapers; then, in a massive wave of transformation from the late nineteenth century, telegraph, radio, photography, film, and television; and finally, the age of digital technology and social media. The media revolutions of 1880–2020 have greatly expanded capacities for making, amplifying, spreading, monitoring, and prosecuting ‘blasphemies’. New media supports new forms of blasphemy. Blasphemous cartoons, ‘blasphemous’ plays and musicals, blasphemy memes, and ‘blasphemies’ and insults which are being auto-generated by algorithms, are important elements in the media revolution. Blasphemy has become an explicit form of advertising and promotion.
