The bridal registry has been around since 1924, when it was introduced at Chicago's Marshall Field's department store. It's become a common custom since it's such a practical way for young couples to get things for their home, while avoiding the possibility of receiving three identical blenders. Of course, your guests don't have to use the registry, but if they do, at least you know you'll like (and use) the present. But in short, why not? You can't fight city hall and in the long road that hopefully will be your marriage, this is an easy one to give up to the missus.
