Barbie at 50: is Mattel's star still in fashion?

Everyone knows barbie.
And its famous around the world.
Even when I used to live in my country barbie dolls were famous.

This year it is barbie's 50th birthday.

Things have changed compared to the first time when it was released. For example,,,

1. Fashion and trend
2. Technology available (production & consumer access such as internet)

Now customers can go to Mattel's website to dress up barbie dolls.

However, no matter how famous the dolls have been it can lose its share if they do not do enough research and some of it must be managing risks.

For instance, they must be up to date on their knowledge about the child's preference.
In addition which types of features they can add and which not to add.
They must constantly balance their cost and revenue so that they can deal with rapid change in the consumer environment.
