The Day Everything Changed: Four Inventions That Split History in Two (Epic Tech)

Some inventions arrive quietly. Others split the world into before and after — and nothing is ever the same again.

The Day Everything Changed takes you inside four of those moments: the software crammed into 72 kilobytes that kept Apollo 11 from crashing into the Moon, the @ symbol that accidentally invented modern communication, a memo marked vague but exciting that became the World Wide Web, and the 90-minute keynote where one man held up a rectangle of glass and obsoleted an entire industry before lunch.

This isn't a book about technology. It's a book about decisions made under pressure, about engineers who stayed up all night, executives who almost killed the project, and the single lines of code — or single keystrokes — that changed the course of history.

Inside this book you'll discover:

• The terrifying software glitch that almost aborted the Moon landing — and the 24-year-old programmer whose decision saved it
• How one character (@) chosen almost at random became the foundation of all digital communication
• Why Tim Berners-Lee's boss wrote vague but exciting on his proposal — and nearly buried the World Wide Web before it existed
• The real story of Steve Jobs' 2007 iPhone reveal — and the industries that never recovered

Written for curious, non-technical readers who love history, storytelling, and the moments where everything could have gone differently, The Day Everything Changed is part thriller, part history lesson, and entirely impossible to put down.
