Questions 196-200 refer to the following news and note.
Now it seems America’s love affair with Barbie may be coming to an end-US sales of Barbie fell 15% in the first quarter this year, which combined with other problems to see overall profits at the Barbie maker Mattel slump by 73%.
Barbie’s career has spanned hundreds of jobs, and her makers have striven valiantly to keep up with the latest trends. Barbie now uses computers and sends text messages on her mobile phone. A Barbie-branded range of designer clothes for girls, and branded perfume are also in the pipeline.
But Mattel’s attempts to keep pace with modern life have not always gone down well with customers. One letter to the New York Times following Barbie’s split from long time partner Ken complained that "the breakup—discourages-even insults-permanence and commitment".
Meanwhile, Barbie has some hip new rivals on the scene. MGA Entertainment’s Bratz doll come in a range of different ethnic groups, and boast fashions described as "totally dangerous, totally ferocious and totally cruel". They have won two Toy Industry Association’s Toy of the Year Award,and figures suggest rising sales are eating directly into sales of Barbie.
But analysts say with thought and investment Barbie could still have a future ahead.
