The popularity and worldwide scope of rock music resulted in a powerful impact on society. Rock and roll influenced daily life, fashion, attitudes and language in a way few other social developments have equalled. As the original generations of rock and roll fans matured, the music became an accepted and deeply interwoven thread in popular culture. Beginning in the early 1950s, rock songs and acts began to be used in a few television commercials; within a decade this practice became widespread, and rock music also featured in film and television program soundtracks.
In the cross-over of African American "race music" to a growing white youth audience, the popularization of rock and roll involved both black performers reaching a white audience and white performers appropriating African-American music. Rock and roll appeared at a time when racial tensions in the United States were entering a new phase, with the beginnings of the civil rights movement for desegregation, leading to the Supreme Court ruling that abolished the policy of "separate but equal" in 1954, but leaving a policy which would be extremely difficult to enforce in parts of the United States. The coming together of white youth audiences and black music in rock and roll, inevitably provoked strong white racist reactions within the US, with many whites condemning its breaking down of barriers based on color. Many observers saw rock and roll as heralding the way for desegregation, in creating a new form of music that encouraged racial cooperation and shared experience. Many authors have argued that early rock and roll was instrumental in the way both white and black teenagers identified themselves.
