Can you tell me what the difference is between a fad and a craze?

Fad is an ephemeral fashion trend that quickly dies out, while a craze is something that becomes popular and lasts for a long time. A fad can be a new product or activity that catches on quickly but then quickly loses its popularity, while a craze is more like a social phenomenon that spreads through word of mouth, creating a lasting interest in it.
