Not so long ago, most companies were family affairs, owned by different members of the same family. Some still are, but now many companies have survived the founding families and grown into big organisations which own smaller, or subsidiary companies. These companies work in other countries to form multi-national groups, such as the big oil companies like Shell or Esso, and the big car manufacturers like Ford. The big multi-national companies each control more money than many countries do. These companies only exist to make profits for their owners, or shareholders.
