Fifty-three years ago Barbie Millicent Roberts first appeared in the world of toys. Since then, Barbie doll, as everyone called her, has become the most successful toy doll in history. Her parent, the Mattel Company, said that 90% of all American girls between 3 and 10 have at least one Barbie at home. However, Barbie is facing some trouble at present( 现在 ). There are many dolls on the market in competition with her. Another doll named Bratz, for example, came to life thir years ago. She looks more like today’s pop stars with heavy makeup( 浓妆 ) and miniskirts. And her company offers more kinds of clothes too. It seems that Barbie has lost her magic among older girls. “For younger girls, playing with a Barbie is much fun. But when you get older, you want something smarter and more modern, ” says Vera Stepherd, a shop assistant in a New York toy store. It is good news that on the international market, Barbie is still No. 1. Although Mattel is selling fewer Barbie’s in the United States these years, sales in other countries are still going up. In January 2009, Mattel opened its first Barbie store in Shanghai, where girls can shop, eat, drink or even become fashion designers for their own Barbies. Mattel is planning big celebrations for Barbie’s 53rd birthday. Fashion designers from all over the world have been called to make new dresses for Barbie. How long will Barbie stay popular in the world of toy dolls? It is hard to say, but 53 is surely not the age to retire(退休) 4. What’s the meaning of the underlined words “fashion designers” in the passage?
