The correct answer is A. It prompted the spending power and fashionable lifestyles of teenagers.
Rock music has an amazing cultural value. This alternative A represents a point of view from both the musicians and the fans. Rock can be considered the first music for the masses. When Elvis Presley became a star in the 50's, the King started a trend gathering a great number of fans, giving birth to a new type of musician, the idol. Elvis became one of the most well known figures of all time and from this point onward, other artists like The Beatles became huge enough to fill soccer stadiums all across the world for their tours whilst also being featured in magazines and pictures. Today, we can see this model of power and consumerism applied for teen idols, sparking different spin-offs like cartoons, dolls and other products.
