Market share is a measure of the relative size of a firm in an industry or market in terms of the proportion of total output or sales or capacity it accounts for.

In addition to profits, one of the frequently cited business objectives of firms is to increase market share. Market share, profits and economies of scale are often positively correlated in market economies. High levels of market share may bestow market power on firms.
