I work in digital creative development with lofty goals of shifting towards television eventually down the line. Something I've noticed more and more as of late when submitting ideas to studios is that you have to sign an agreement which basically says, "just because you send us your idea, we turn it down, but then we later produce something that seemed similar to your idea, does NOT mean we stole your idea." It practically suggests that in an age where so many people are producing ideas, attempting to submit them for development and so on, that it's near impossible for you to create a truly original idea. It's touched on in this article: ideas are a dime a dozen, and while anyone can say, "I came up with something JUST like that!", that's far different from "I saw that idea through from conception to completion."
