Just learned from *The Wisdom of Crowds* that there was a "Bowling Company Stock Bubble" in the fifties. After the invention of the automatic pin-setting machine, bowling company stocks were the darlings of Wall Street. Predictions about how the market would continue to expand at an amazing rate, yada.
Right now, we may be in a videogame stock bubble: Take Two, EA, and Activision stock have been pretty much tracking each other for years now, continually beating the market by a wide margin. Wall Street continues to predict that the industry will expand.
But what if videogames are like bowling? A fad buoyed along by some new technology that will lose its interest in a year or several?
I don't really believe it--bowling was just one game, but videogames are...lots of games--but I do admit that maybe it's a possibility.
