- Version History released its season-five finale on The Verge, dedicated to the history of the overhead projector in American classrooms
- The episode is hosted by David Pierce with Verge reporter Jake Kastrenakes and Stanford professor Antero Garcia, tracing the OHP from military roots to widespread classroom adoption
- The discussion explicitly poses whether modern replacements — PowerPoint, computer screens, and smart boards — actually improved on the overhead projector
- Season five also covered Oregon Trail, the original Chromebook, the One Laptop Per Child program, the LeapFrog LeapPad, and Texas Instruments calculators
- The OHP became dominant because it let teachers face students while writing, eliminating the disciplinary opening created by chalkboard instruction
- The podcast frames the OHP's decline as an unresolved question rather than a clear upgrade, asking why the tool has 'mostly gone away'
Why it matters: By framing the OHP's replacement as an open question rather than a settled improvement, the episode complicates the standard narrative that classroom tech has steadily improved — a challenge aimed squarely at the smart-board-and-Slides orthodoxy in modern schools.
