Gruner + Jahr is a publishing house headquartered in Hamburg, Germany. The company was founded in 1965 by Richard Gruner [de], John Jahr [de], and Gerd Bucerius. From 1969 to 1973, Bertelsmann acquired a majority share in the company and gradually increased it over time. After 2014, the company was a fully owned subsidiary of the Gütersloh-based media and services group. Under the leadership and innovation strategy of Julia Jäkel, Gruner + Jahr evolved into a publishing house producing cross-channel media products for the digital society.
