@Jlauro: "There will never be only one standard. Too boring, no room for innovation... at best there may be a leading format for a decade, and if it's lucky it will continue to be the lading for the next, etc..."
A valid thought process, but one thing: the movie industry hasn't stayed the same always, either. We had VHS for about 15 years, then shifted to DVD. Also, the console industry does this anyway, with each major manufacturer coming up with a new and improved format LESS than a decade later. So, forgive me, but I'm not sure what you're trying to show?
