A ripple effect is a situation in which ripples expand across the water when an object is dropped into it, an effect from an initial state can be followed outwards incrementally.
In sociology, it can be observed how social interactions can affect situations not directly related to the initial interaction,[page needed] and in charitable activities where information can be disseminated and passed from community to community to broaden its impact.
The concept has also been applied to financial markets to describe the impact of a given event and how it propagates through the players in the industry and its effect on stock price and stock coverage.
