Problem: Years ago, before the iPod could hold up to 1,000 to 5,000 songs, Sony created a portable device called the Walkman. In fact, for decades, Sony dominated the portable music industry. However, today Apple dominates the portable music industry. Research the Walkman's market dominance in the 1980s and after analyzing the facts, give your opinion as to why you believe Sony lost its place in the industry and, from a consumer's standpoint, what you believe to be Apple's competitive advantage by introducing the iPod? In addition, why did Apple buy Dr. Dre Beats? Do you think Apple is trying to prevent becoming another Sony?
