A fad or a trend

A fad is short-lived while a trend is more of a manifestation of some product or service that has unlocked or changed an existing consumer need, desire, want, or value The pizza cone is but just an exaggerated craze for fun food.

Years ago, bubble tea houses mushroomed all over Singapore and were ubiquitous. Now, only a handful or even less have survived. A fad.

I heard the same phenomenon happening to donuts/doughnuts in Singapore recently. Years ago, there was Dunkin Donuts in Singapore but it died. Now, donuts relived again. But what will be the lifespan, I wonder. I think it is just another fad.

I think that starting or following a fad is itself a trend. HA!
