The saying goes that there's "...nothing new under the sun" meaning that many inventions and Innovations are a combination of previous elements or improvements on a pre-existing Idea. Given our current highly technical society we may think that we're the ones who have made the biggest contributions to innovation. I sometimes see blog posts or articles where the author thinks that they have just discovered something so new and brilliant. Not always true. I came across a post last year where the author had just "invented a new way of brainstorming." Actually the Greeks had used this technique over a couple of thousand years ago based on the famed Oracle of Delphi. During the 1950s both the government and the Rand corporation take credit for formalizing it into the "Delphi Method."
