In the twentieth century, dating was sometimes seen as a precursor to marriage but it could also be considered as an end-in-itself, that is, an informal social activity akin to friendship.
It is a form of courtship, consisting of social activities done by the couple, either alone or with others.
With the use of modern technology, people can date via telephone or computer or meet in person.
Dating may also involve two or more people who have already decided that they share romantic or sexual feelings toward each other.
Thus, the concept of marriage is changing widely in many countries.
Historically, marriages in most societies were arranged by parents and older relatives with the goal not being love but legacy and "economic stability and political alliances", according to anthropologists.
