Over the past forty-five years, computers have transformed nearly every aspect of modern life.

The narrative examines the key developments that shaped the digital age.

Quick Summary

If your kid is curious about how we got from room-sized computers to the devices we use today, this one's a great pick. Charles A. Jortberg takes readers through the remarkable growth of computers over the past few decades, showing up close how they changed everything from business operations and air traffic control to the space program. The book really shines when it connects those giant "big machines" to things kids actually recognize today, making history feel relevant instead of dusty. It's perfect for middle graders who love learning how things work, whether they're into technology, space, or just enjoy impressing people with random facts. The writing stays accessible without talking down to kids, so even reluctant readers can power through it. Parents will appreciate that it's solid nonfiction that answers real questions about the world without being preachy. If your young reader enjoyed books about inventions or the history of technology, they'd likely gravitate toward this one too.
