Here is how things become trendy. There are a bunch of things with lots of potential to become… and thats the problem, there are lots of things. In order for of these things to become cool, they have to gain momentum and exsposure. Once a thing gets picked up it will start gaining in coolness at a variable rate.
If the rate of coolness increase is not enough the thing will simply fizzle. It will not attract enough interest maintain it’s coolness and perpetuate itself. People wil get interested in other things, like basket weaving, and it will simply fizzle.
However if the rate of coolness increase is too great, the thing will peak and start a coolness descent. There is usaully a distinct tipping point refered to as the coolness peak. This peak is usaully associated with too much exsposure or a sudden increase in accesibility.
In order for a thing to have maintainable coolness it needs a moderate increase of coolness that is just enough to allow it to slowly perpetuate. It helps to have a small core following that slowly expands. Once a thing has been cool for a long enough amount of time it is becomes embed in the culture of a group, it gains the much sought after iconic status.
