The Fed Cup is the women's equivalent of the Davis Cup. It was first held 63 years after the creation of the men's event, under the name of the "Federation Cup", to celebrate the 50th anniversary of the International Tennis Federation. Unlike the Davis Cup, it has always been open to all nations.The format from 1963 through to 1995 saw a week-long event held at a different venue each year. In 1992, regional qualifying matches were introduced as the volume of entries made it impractical to host a single tournament. Three years later the competition was re-named the Fed Cup and adopted the Davis Cup format, although the "World Group" consists of eight, as opposed to 16, nations.
