The fathers' rights movement exists almost exclusively in industrialized countries, where divorce has become more common. It emerged in the West from the 1960s onwards as part of the men's movement with organizations such as Families Need Fathers, which originated in the 1970s. In the late twentieth century, the growth of the internet permitted wider discussion, publicity and activism about issues of interest to fathers' rights activists. Factors thought to contribute to the development of the fathers' rights movement include shifting household demographics brought about by rising divorce and falling marriage rates, changes in the understanding and expectations of fatherhood, motherhood and childhood as well as shifts in how legal systems impact families.
