When something becomes fashionable very quickly , we say that it’s a “craze”. The latest  craze is sometimes a style of clothes or a hairstyle. Sometimes it is a game or a TV programme.

In the 20th century a lot of crazes started in the USA and then became popular in the USA and then became popular in other parts of the world. American youth culture has spread through tourism , TV , films, magazines and music videos.

One of the biggest crazes was the hula hoop（呼啦圈）. Hula hoops are not popular now, but  in the1950s they were a sensation.  An American company called Wham-O started to make plastic（塑料的）hoops toys, and in the USA the company sold 100 million hoops in a year.

Frisbees（飞盘）were another Wham-O product（产品）. Some people say that the idea

started in the factory of the Frisbee Baking Company in Connecticut. Workers there threw metal  pans to each other during their breaks. Two businessmen made a plastic type of the flying pans,  and sold their products to Wham-O. They became a big business.

So businesses usually help to produce a craze. Yoyos were another example. In the Philippines,  where its name means “comeback”, the yoyo was a popular toy in the 1920s. But  it didn’t become a global (世界性的) craze until an American called Donald Duncan bought the  idea and sold it to the world. Around 100 million people bought yoyos in 1962 and 1963.

Most crazes come and go, but sometimes they survive. When the big skateboard started in California in 1965, many parents and governments said that the boards were dangerous, and they  were not allowed in some areas. But the boards became popular again and they are still an important part of youth culture today.
