What are fads?

What will be an ideal response?

Fads are fashions that come quickly into public view, are adopted with great zeal, peak early, and decline very fast. Their acceptance cycle is short, and they tend to attract only a limited following who are searching for excitement or want to distinguish themselves from others. Fads fail to survive because they don't normally satisfy a strong need. The marketing winners are those who recognize fads early and leverage them into products with staying power.
