OK it's Wikipedia but this paragraph is interesting.
In social sciences, a voluntary standard that is also a de facto standard is a typical solution to a coordination problem.[1] The choice of a de facto standard tends to be stable in situations in which all parties can realize mutual gains, but only by making mutually consistent decisions. In contrast, an enforced "de jure standard" is a solution to the prisoner's problem.[1]
