Can some market creation opportunities be simply too big for a single business or organization to own? Is there such a thing as Too Big to Nail? Twitter and Craigslist are potential modern examples. My former employer, Xerox (in the form of the early technologies created at PARC) is a possible historical example. In a live tweetstorm earlier this week, I improvised a rough argument that are indeed too-big-to-nail opportunities, and suggested the term 'supernova companies' for startups that discover such markets. Several people asked for a more thorough, longform version of the argument, but this would require a very careful and time-consuming analysis of historical data (which I don't have). But, here's a cleaned up and 2x expanded version of the original tweetstorm, with some quick thoughts on how to play in supernova markets.
