Failure (or flop) in general refers to the state or condition of not meeting a desirable or intended objective. It may be viewed as the opposite of success.
The criteria for failure are heavily dependent on context of use, and may be relative to a particular observer or belief system. A situation considered to be a failure by one might be considered a success by another, particularly in cases of direct competition or a zero-sum game. As well, the degree of success or failure in a situation may be differently viewed by distinct observers or participants, such that a situation that one considers to be a failure, another might consider to be a success, a qualified success or a neutral situation.

It may also be difficult or impossible to ascertain whether a situation meets criteria for failure or success due to ambiguous or ill-defined definition of those criteria. Finding useful and effective criteria, or heuristics, to judge the success or failure of a situation may itself be a significant task.
Failure can be differentially perceived from the viewpoints of the evaluators. A person who is only interested in the final outcome of an activity would consider it to be an Outcome Failure if the core issue has not been resolved or a core need is not met. A failure can also be a process failure whereby although the activity is completed successfully, a person may still feel dissatisfied if the underlying process is perceived to be below expected standard or benchmark.
A commercial failure is a product that does not reach expectations of success, failing to come even close. A major flop goes one step further and is recognized for its complete lack of success.

Most of the items listed below had high expectations, significant financial investments, and/or widespread publicity, but fell far short of success. Obviously, due to the subjective nature of "success" and "meeting expectations", there can be disagreement about what constitutes a "major flop."
