In most cases, a company described as "bigger" has a larger sphere of influence. For example, the software company Microsoft has a large sphere of influence in the market of operating systems; any entity wishing to sell a software product may weigh up compatibility with Microsoft's products as part of a marketing plan.
The Anglosphere is the Anglo-American sphere of influence. [ a ] The term was first coined by the science fiction writer Neal Stephenson in his book The Diamond Age , published in 1995. John Lloyd adopted the term in 2000 and defined it as including English-speaking countries like the United Kingdom, the United States, Canada, Australia, New ...
The Hill sphere is a common model for the calculation of a gravitational sphere of influence. It is the most commonly used model to calculate the spatial extent of gravitational influence of an astronomical body ( m ) in which it dominates over the gravitational influence of other bodies, particularly a primary ( M ). [ 1 ]
A sphere of influence (SOI) in astrodynamics and astronomy is the oblate spheroid-shaped region where a particular celestial body exerts the main gravitational influence on an orbiting object. This is usually used to describe the areas in the Solar System where planets dominate the orbits of surrounding objects such as moons , despite the ...
America's backyard is a concept often used in political science and international relations contexts to refer to the sphere of influence of the United States and its traditional areas of dominance, especially Latin America. It is somewhat analogous to the Russian concept of near abroad (Russian: ближнее зарубежье, blizhneye ...
Using the title of a settlement can be misleading in the absence of any widely accepted definition. For example, city status in the United Kingdom historically arose from its place in the ecclesiastic hierarchy. (In modern times, city status is awarded for secular reasons but without reference to size.)
The gravity model can also be used to determine the sphere of influence of each central place by estimating where the breaking point between the two settlements will be. An example of this is the point at which customers find it preferable, because of distance, time and expense considerations, to travel to one center rather than the other.
Sphere of influence (black hole), a region around a black hole in which the gravitation of the black hole dominates that of the host bulge; Sphere of influence, an area or region over which a state or organization has significant cultural, economic, military or political influence; Sphere of influence is also a legal term in family law.
