Whiteboard

The whiteboard emerged in the 1960s, though its origin is contested. One account credits Martin Heit, a Korean War veteran and photographer, who noticed that markings on the enameled steel surface used for his film negatives could be wiped away easily with a dry cloth.1 He recognized the surface's potential as a reusable writing surface and began developing dry-erase boards for commercial use.

Early versions were called "marker boards" or "dry-erase boards." The first commercial products appeared in the late 1960s and early 1970s, manufactured by companies including Dri-Mark and Quartet. Adoption was slow. Whiteboards were significantly more expensive than chalkboards, and many schools and offices saw no reason to replace a system that already worked.2

By the 1990s, whiteboards had overtaken chalkboards in American offices and were gaining ground in classrooms. The shift was driven partly by concerns about chalk dust and partly by the cleaner aesthetic of a white surface in modern office design.3 The whiteboard became the default surface for brainstorming sessions, project planning, and the improvisational visual thinking that meeting rooms were designed to encourage.

Digital whiteboards appeared in the 2010s, and software tools like Miro and Mural created virtual whiteboard environments for remote collaboration after 2020. The physical whiteboard remains ubiquitous in technology companies, where the ability to stand up, walk to a wall, and draw an idea remains a fixture of how teams think together.4
