In a time of sweeping media change, the four major networks struggle for the attention of American viewers increasingly distracted by cable, video games, and the Internet. Behind boardroom doors, tempers flare in the search for hit shows, which often get on the air purely by accident. The fierce competition creates a pressure-cooker environment where anything can happen.

Think of an important moment in live TV over the last half-century. Dick Ebersol was likely involved. Dropping out of college to join the crew of ABC’s Wide World of Sports, Ebersol worked the Mexico City Olympics during the famous protest by John Carlos and Tommie Smith as well as the Munich Olympics during the tragic hostage standoff. He went on to cocreate Saturday Night Live with Lorne Michaels and later produced the show for four seasons, helping launch Eddie Murphy to stardom.

Barbra Streisand is by any account a living legend, a woman who in a career spanning six decades has excelled in every area of entertainment. She is among the handful of EGOT winners (Emmy, Grammy, Oscar, and Tony) and has one of the greatest and most recognizable voices in the history of popular music. She has been nominated for a Grammy 46 times, and with Yentl she became the first woman to write, produce, direct, and star in a major motion picture. In My Name Is Barbra, she tells her own story about her life and extraordinary career.

HBO changed how stories could be told on TV. The Sopranos, Sex and the City, The Wire, Game of Thrones. The network’s meteoric rise heralded the second golden age of television with serialized shows that examined and reflected American anxieties, fears, and secret passions through complicated characters who were flawed and often unlikable.

Robert Iger became CEO of The Walt Disney Company in 2005, during a difficult time. Competition was more intense than ever, and technology was changing faster than at any time in the company’s history. His vision came down to three clear ideas: Recommit to the concept that quality matters, embrace technology instead of fighting it, and think bigger - think global - and turn Disney into a stronger brand in international markets.
