The dramatic upheaval comes 11 months after Iger left Disney, and days after Chapek said he planned to cut costs at the company, which had been burdened by swelling costs at its streaming service, Disney+.Chapek was named chief executive in February 2020, succeeding Iger, who had previously said he wouldn't return to the role.Iger has signed on to work as CEO for two years, Disney said Sunday, "with a mandate from the Board to set the strategic direction for renewed growth and to work closely with the Board in developing a successor to lead the Company at the completion of his term."When I look at the creative success of our teams across our Studios, Disney General Entertainment, ESPN and International, the rapid growth of our streaming services, the phenomenal reimagining and rebound of our Parks, the continued great work of ABC News, and so many other achievements across our businesses, I am in awe of your accomplishments and I am excited to embark with you on many new endeavors.I know this company has asked so much of you during the past three years, and these times certainly remain quite challenging, but as you have heard me say before, I am an optimist, and if I learned one thing from my years at Disney, it is that even in the face of uncertainty—perhaps especially in the face of uncertainty—our employees and Cast Members achieve the impossible."
