Final answer:
Outer-space satellites are an example of a modern device that first appeared in books or stories, predating their real-world creation. Literature, especially science fiction, often paves the way for technological advancements by imagining future innovations.
Step-by-step explanation:
One example of a modern device that first took form in a book or story is the concept of outer-space satellites. In literature, particularly science fiction, many concepts of modern technology were explored long before they were physically created. For instance, the idea of devices orbiting the Earth to provide communication and other services was popularized in stories and novels before becoming a reality. The Sony Walkman and portable MP3 players, similar in spirit to the devices we use today to listen to music, are other examples of technology that was first imagined in creative literature and later developed into tangible products we use in our everyday lives.
