This case traces the 30-year development of the rock band U2 and the development of its four members as artists, business leaders, and humanitarians (with particular attention paid to lead singer Bono's global humanitarian work). The case examines the beginnings of the band among four school friends and follows the development of the enterprise as a business and as a powerful social and cultural force in its own right. It also investigates the individual journeys of the band members during moments of great success and significant challenges. The case pays particular attention to the four men's evolving identities as musical artists and to the tradeoffs that have accompanied their fame and larger social commitments. The case takes up the evolution of the global music industry in the face of rapid technological and organizational change, examining how U2 and colleagues navigated such change, built a very powerful brand, and created a successful business model. The final part of the case traces lead singer Bono's involvement in political and humanitarian causes and the potential power of such a model as a framework for artistry, entrepreneurship, and effective leadership in the 21st century.

The case explores the entrepreneurial journey of Oprah Winfrey, examining how she built an audience for one of the most successful television shows in history; how she created the company, Harpo Productions, that produces that show as well as other media offerings; how she leads and manages her organization; and how she has chosen to use the authority and other fruits of success to make a significant social as well as business contribution. The case uses interviews with Winfrey and her team to analyze how the business model and strategy of the company has changed-in the context of a dynamic marketplace, rapid technological innovation and Winfrey's own evolving conception of her purpose and path.
