I think JJG pretty well has it nailed. In a nutshell, better informed consumers created increased demand for better quality and more variety. A similar scenario has occurred in micro brew beers in the last decade or so. People bought the major brands because that was what was available. Once some of the micro brews started becoming more available, people "woke up" to the varieties that were available. Competition increased, and quality went up, selection went up, even the quality of the hops, malt, etc. increased.
