What is Hello Kitty?
Hello Kitty is a fictional character who originated in Japan. She is a white cat who dresses in children's clothes and wears a pink bow on her head.
While Hello Kitty was created in 1974, she got big in the 1990s and 2000s, appearing on lunchboxes, jewelry, stationery, and nearly every other type of product you can think of. Now, there are Hello Kitty TV shows, comics, coffee shops, and even theme parks, and HK remains popular among girls (and some others) of all ages.
