A riveting, insider's look at the creation and evolution of the like button, and what it reveals about business, technology, and innovation-and us.

Over seven billion times a day, someone taps a like button.

How could something that came out of nowhere become so ubiquitous and so familiar-and even so addictive? What problem does it solve for people, and why does a "like" feel so good? And by the way, who invented the like button in the first place?

In Like, bestselling author and renowned strategist Martin Reeves and coauthor Bob Goodson-Silicon Valley veteran and participant in the invention of the like button-take readers along on a fascinating quest to find out what's behind the world's friendliest icon. It's a story that starts out as simply as a thumbs-up cartoon but ends up presenting surprises and new mysteries at every turn, some of them as deep as anthropological history and others as speculative as the AI-charged future.

But this isn't just the story of the like button. It's so much more.

Using the origin story and evolution of the like button as a jumping-off point, the authors take readers on a fun and fascinating journey through the world of business, offering smart and surprising insights into technology, innovation, creativity, invention, and even us.

For such a small and unassuming invention to take on such scale and power, it must be tapping into something very, very big.
