Much of Fahrenheit 451 is devoted to depicting a future United States society bombarded with messages and imagery by an omnipresent mass media. Instead of the small black-and-white TV screens common in American households in 1953 (the year of the book's publication), the characters in the novel live their lives in rooms with entire walls that act as televisions. These TVs show serial dramas in which the viewer's name is woven into the program and the viewer is able to interact with fictional characters called "the relatives" or "the family." Scenes change rapidly, images flash quickly in bright colors, all of it designed to produce distraction and fascination. When not in their interactive TV rooms, many characters, including Guy Montag's wife Mildred, spend much of their time with "Seashell ear thimbles" in their ears—miniature radio receivers that play constant broadcasts of news, advertisements, and music, drowning out the real sounds of the world.
Throughout the novel, Bradbury portrays mass media as a veil that obscures real experience and interferes with the characters' ability to think deeply about their lives and societal issues. Bradbury isn't suggesting that media other than books couldn't be enriching and fulfilling. As Faber tells Montag, "It isn't books you need, it's some of the things that once were in books.... The same infinite detail and awareness could be projected through the radios and televisors, but are not." In an interview marking the fiftieth anniversary of the novel's publication, Bradbury indicated that some of his fears about mass media had been realized. "We bombard people with sensation," he said, "That substitutes for thinking."
