Bertelsmann is growing and needs new organizational structures. With the establishment of Bertelsmann AG, a new management structure is created. Increasing headcounts necessitate a new head office, and the company moves to its new headquarters in 1976. In 1981, the year of his 60th birthday, Reinhard Mohn hands over the chairmanship of the Executive Board to Manfred Fischer, who has served as CEO of Gruner + Jahr to date. In the following years, Reinhard Mohn dedicates himself to establishing the Bertelsmann Stiftung, which he founds in 1977. Mark Wössner, Chairman of the Executive Board from 1983, brings the company back on track for growth. With two major acquisitions in the United States (Doubleday and RCA) in 1986, Bertelsmann manages a breakthrough in the world’s biggest media market. The entry into commercial television in Germany two years earlier is already an expression of a changed understanding of the media, and testament to the Group’s undiminished ability to take innovative entrepreneurial steps. Immediately after the fall of the Berlin Wall, the Group expands in East Germany: In December 1989, a Club Bertelsmann branch opens in Dresden.
