This means that a business that had previously only sold its goods domestically can start selling products to other countries. One example of expanded markets includes the auto industry. Before the fall of the Berlin Wall, those living in countries under the influence of communism only had access to cars that were produced domestically or in other communist markets. This was due to trade barriers with the West. When communism fell, Western economies, that is, countries that were not under communist influence, were able to expand their markets to former communist countries. This in turn increased their profit potential.
