What qualifies 1984 as a science fiction novel?

Science fiction is a genre in which the writer uses the impact of actual or imagined science to create a future or an alternate world. Good science fiction creates a world the reader finds plausible. Some science fiction is very reliant on advances in science; other science fiction is based more on sociology than hard science and often serves as social criticism. Examples are Ray Bradbury’s Fahrenheit 451 and Aldous Huxley’s Brave New World. 1984 is the latter kind of science fiction, based on sociology more than technology or scientific advancements of Orwell’s own time. The invention of televisions that transmit both ways is one of the few examples of hard science/technology in 1984. However, most of the novel explores the consequences of totalitarianism, a social construct, run rampant.
