Everyone thinks they know the Internet. The most powerful information network ever conceived—an indispensable tool and constant companion in both our professional and personal lives. We’re all connected but connected to what? As Andrew Blum explains, the Internet exists: it fills buildings, converges in some places in the world and avoids others, and it flows through tubes, along train lines and highways, and under oceans. You can map it, you can smell it, and you can see it. Blum goes behind-the-scenes of our everyday lives and combines first-rate reporting, engaging and lucid explanation into a fast-paced quest to explain the world we live in. From the room in L.A. where the Internet began to the busiest streets in Manhattan as new fiber optic cable is laid down; from the coast of Portugal as a new transatlantic undersea cable that connects West Africa and Europe is laid down to the Great Pyramids of our time, the monumental data centers that Google and Facebook have built in the wilds of Oregon—Blum visits all the hot spots to chronicle the dramatic story of the Internet’s development and explain how it all works.
