Financial bubbles have existed for only marginally less time than investment markets themselves. This is because our tendency to get excited and carried away causes them.
There is, however, a serious risk of misusing the term 'bubble'. It metaphorically implies an obvious ending: the bubble bursts. And we all know how that happens: very quickly, and very violently. You simply can't pop a bubble gradually. Physics won't allow it.
