If you loved Hidden Figures or The Rise of the Rocket Girls, you'll love Claire Evans' breakthrough book on the women who brought you the internet--written out of history, until now.

"This is a radically important, timely work," says Miranda July, filmmaker and author of The First Bad Man.The history of the internet is more than just alpha nerds, brogrammers, and male garage-to-riches billionaires. Female visionaries have always been at the vanguard of technology and innovation. In fact, women turn up at the very beginning of every important wave in technology. They may have been hidden in plain sight, their inventions and contributions touching our lives in ways we don't even realize, but they have always been part of the story.In a world where tech companies are still male-dominated and women are often dissuaded from STEM careers, Broad Band shines a much-needed light on the bright minds history forgot, from pioneering database poets, data wranglers, and hypertext dreamers to glass ceiling-shattering dot com-era entrepreneurs. Get to know Ada Lovelace, who wove the first computer program in 1842, and Grace Hopper, the tenacious mathematician who democratized computing after World War II. Meet Elizabeth "Jake" Feinler, the one-woman Google who kept the earliest version of the Internet online, and Stacy Horn, the New York cyberpunk who ran one of the world's earliest social networks out of her New York City apartment in the 1980s.Join the ranks of the pioneers who defied social convention to become leaders of the tech revolution. This electrifying corrective to tech history introduces us all to our long-overlooked tech mothers and grandmothers--showing us that if there's a "boy's club" that dominates Silicon Valley today, it's an anachronism.
