Although joint ventures have been used for decades as a way to organize a business, in recent years they have been used much more widely. They have enjoyed such a surge of popularity, in fact, that more joint ventures have been announced since 1981 than in all previous years. Even U. S. multinationals began to consider joint ventures when entering a new business. Some observers predict that joint ventures are the wave of the future for reasons such as heightened global competition, increased risk and the fast pace of technological change. Many joint ventures are not intended to fill standard businessobjectives (such as making profits). Instead, they were created to learn a technology, open a market and block a competitor.
