End of World War II

From 1941 and the German attack on the Soviet Union, the Allied Coalition operated on the unwritten assumption that the Western Powers and the
Soviet Union The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen nationa ...
had each its own sphere of influence. The presumption of the US-British and Soviet unrestricted rights in their respective spheres began to cause difficulties as the Nazi-controlled territory shrank and the allied powers successively liberated other states. The wartime spheres lacked a practical definition and it had never been determined if a dominant allied power was entitled to unilateral decisions only in the area of military activity, or could also force its will regarding political, social and economic future of other states. This overly informal system backfired during the late stages of the war and afterward, when it turned out that the Soviets and the Western Allies had very different ideas concerning the administration and future development of the liberated regions and of Germany itself.

s; any entity wishing to sell a software product may weigh up compatibility with Microsoft's products as part of a marketing plan. In another example, retailers wishing to make the most profits must ensure they open their stores in the correct location. This is also true for shopping centers that, to reap the most profits, must be able to attract customers to their vicinity. There is no defined scale measuring such spheres of influence. However, one can evaluate the spheres of influence of two shopping centers by seeing how far people are prepared to travel to each shopping center, how much time they spend in its vicinity, how often they visit, the order of goods available, etc. Corporations have significant influence on the regulations and regulators that monitor them.
