"A vertical movement toward market incentives is noticeable, nonetheless. As industrial capitalism arises in England in the eighteenth century, new economic structures raise the stakes for commercial ventures: tantalizing rewards lure innovators into private enterprise, and the codification of English patent laws in the early 1700s gives some reassurance that good ideas will not be stolen with impunity. Despite this new protection, most commercial innovation during this period takes a collaborative form, with many individuals and firms contributing crucial tweaks and refinements to the product. The history books like to condense these slower, evolutionary processes into eureka moments dominated by a single inventor, but most of the key technologies that powered the Industrial Revolution were instances of what scholars call "collective invention." Textbooks casually refer to James Watt as the inventor of the steam engine, but in truth Watt was one of dozens of innovators who refined the device over the course of the eighteenth century." --
