Rock and roll emerged in the postwar United States as a reflection of societal changes and tensions between youth and adults. The economic boom and rise of consumerism empowered teenagers as a demographic with disposable income. Rock music appealed to white teenagers through its blend of blues, country, and gospel influences as well as its overt sexuality. Though controversial for its perceived rebelliousness, rock and roll came to define youth culture of the 1950s and profoundly shaped popular music and fashion going forward.
