Another world-changing idea!
Right, you had a question. Copyrights don't protect ideas, only their expression. So, for example an idea for a software game about angry birds cannot be protected. However, the Angry Birds application that actually performs this task -- and enslaves and distracts millions of healthy minds -- can be protected under copyright law (and patent law if it's novel and not obvious). Names for products and services can usually be protected under trademark law. Here's where you can read more about copyrights, patents, and trademarks.
