Over the first year that Wham-O produced hoops more than 100 million were sold. After the first year the craze of hula hooping in the United States died down. Wham-O decided that they would reproduce the hula hoop and add ball bearings to the inside to make sounds.

This helped bring hula hooping back in a big way and it started the National Hula Hoop Contest. Around 2 million people were in this competition through out 2,000 cities. Wham-O became famous for their innovations on the hula hoop, however they were not able to call the design their own because of the hula hoop's historic background. They were able to trademark "hula hoop" as the name of thier product.
Hula hoops became a big part in the circus around the 1960's through out Chinese, Russian, Australian, and many other cultures. Today the world of hula hooping has blossomed into many different forms.
