"Ohio Art saw his idea at the Nuremberg Toy Fair in 1959. The toy, with its gray screen, red frame and two white knobs that are twisted back and forth to create drawings, was launched in 1960 and became the top seller that holiday season. More than 100 million have been sold worldwide since."
Wow, that must have grossed over a billion in today's dollars. There's a billion-dollar idea for you.
Indeed. Reading the Wikipedia entry on Cassagnes I wonder: 'idea' or 'discovery'?
"Cassagnes, an electrician at the Lincrusta Company, was performing a routine installation of a factory light switch plate wrapped in a translucent decal covering. During the installation, he removed the decal and wrote on it with a pencil, noticing that image transferred to the opposite face. Cassagnes tinkered with his discovery, which led to the world's first prototype of the Etch A Sketch."
I love these stories of something chanced upon by accident being turned into a product. It wouldn't surprise me if most successful ideas come about this way, rather than from a 'visionary' entrepreneur brainstorming the 'next big thing'.
