In business, economics, or marketing, first-mover advantage, or FMA, is the advantage gained by the initial ("first-moving") significant occupant of a market segment. It may be also referred to as Technological Leadership. This advantage may stem from the fact that the first entrant can gain control of resources that followers may not be able to match.Sometimes, first-movers are rewarded with huge profit margins and a monopoly-like status. Other times, the first-mover is not able to capitalize on its advantage, leaving the opportunity for later entrants to compete effectively and efficiently versus the earlier entrants. These firms then may gain a second-mover advantage.
