Patent-level origin: A key early patent for a “clicker/clacker” style toy was filed in 1968 by Willard S. Smith (often referenced as a foundational design tied to the mass-market clacker concept).

Mass popularity: While many companies produced and branded versions during the craze, the core concept spread quickly and became a category toy rather than a single-brand item in public memory.
