It would be more accurate to say the laws of physics push certain services to capture enormous market share. How can a new search engine - or email service, for that matter - compete with Google's servers? How can a new social network compete with Facebook having all your friends already on it? How can a new encyclopedia compete with Wikipedia's vast store of volunteer-checked knowledge? How can a new operating system compete with the fact that everyone already knows hw to use Windows? It's not impossible, but an incremental improvement won't do it; you need to be massively better than the default to overcome the sheer advantage that comes from being the default.
