How are risk, revenue, costs, and profit related in business?

"Creating a quality of life is not without risks, however. Risk is the potential to lose time and money or otherwise not be able to accomplish an organization’s goals. Without enough blood donors, for example, the American Red Cross faces the risk of not meeting the demand for blood by victims of disaster. Businesses such as Microsoft face the risk of falling short of their revenue and profit goals. Revenue is the money a company receives by providing services or selling goods to customers. Costs are expenses for rent, salaries, supplies, transportation, and many other items that a company incurs from creating and selling goods and services. For example, some of the costs incurred by Microsoft in developing its software include expenses for salaries, facilities, and advertising. If Microsoft has money left over after it pays all costs, it has a profit . A company whose costs are greater than revenues shows a loss. When a company such as Microsoft uses its resources intelligently, it can often increase sales, hold costs down, and earn a profit. Not all companies earn profits, but that is the risk of being in business. In U.S. business today, there is generally a direct relationship between risks and profit: the greater the risks, the greater the potential for profit (or loss). Companies that take too conservative a stance may lose out to more nimble competitors who react quickly to the changing business environment. Take Sony, for example. The Japanese electronics giant, once a leader with its Walkman music player and Trinitron televisions, steadily lost ground—and profits—over the past two decades to other companies by not embracing new technologies such as the digital music format and flat-panel TV screens. Sony misjudged what the market wanted and stayed with proprietary technologies rather than create cross-platform options for consumers. Apple, at the time an upstart in personal music devices, quickly grabbed the lion’s share of the digital music market with its iPods and iTunes music streaming service. By 2016, Sony restructured its business portfolio and has experienced substantial success with its PlayStation 4 gaming console and original gaming content."
