From 1963, the Beatles provided one of the first opportunities for female teenagers in Britain to exhibit spending power and publicly express sexual desire, while the group's image suggested a disregard for adults' opinions and parents' ideas of morality. In the description of author and musician Bob Stanley, the band's domestic breakthrough represented a "final liberation" for the nation's teenagers and, by coinciding with the end of National Service, the group "effectively signaled the end of World War II in Britain".
