Michael Eisner took over as CEO of Disney in 1984 when the company was struggling financially. To rejuvenate Disney, Eisner diversified the company into new markets targeting both children and adults. He increased net income over four years through strategies like creating movies and TV shows for adult audiences, opening Disney stores, and purchasing a TV station. This diversification strategy succeeded according to Porter's tests by entering attractive new markets with low costs. As a result, Disney's net income increased over five times from $98 million in 1984 to $522 million in 1988, while total revenue grew from $1.656 billion to $3.438 billion over the same period.
