Claire L. Evans' Broad Band isn't just another tech history book—it's a revelation. As someone who spends hours daily immersed in digital worlds, I was shocked by how many foundational female pioneers I'd never heard of. The way Evans weaves technical details with deeply human stories makes complex concepts like packet switching feel as engaging as a novel.

The first third had me literally gasping—learning how Ada Lovelace's 1840s algorithms foreshadowed modern programming while her male contemporaries dismissed her work gave me chills. The middle section does lose some momentum when covering 90s internet culture, but even then, discovering women like Jaime Levy (inventor of early digital magazines) made me pause my reading to Google their innovations.

What surprised me most? Realizing how many 'male genius' narratives in tech documentaries actually built on these women's breakthroughs. That moment when you're reading about Stacy Horn's pre-AOL social network Echo and think 'Wait—she basically invented online communities?' happens constantly.

The paperback's thin pages do require careful handling (I dog-eared several important passages), and non-native English speakers might find some technical jargon challenging. But as both an educational text and corrective to Silicon Valley mythology, this belongs on every tech enthusiast's shelf—right next to your Walter Isaacson biographies, where the contrast will speak volumes.
