Because, there are many different ways to answer your question, depending on where you're coming from exactly and what your intentions are.
For example, one thing one could do if they wanted to market a brilliant idea they had and turn it into a prototype and potential small business of their own is to leverage something like kickstarter.com. There are very interesting projects there all the time, where inventors/entrepreneurs present great ideas and seem them come to fruition based on the community's efforts (aka "crowdsourcing").
Yeah?
