History 1940s In 1946, publisher Hinrich Springer (age 66) and his son Axel Springer (age 34) established the limited company Axel Springer Verlag GmbH. That year saw the launch of the Nordwestdeutsche Hefte and the radio and TV magazine Hörzu. In 1948, the evening newspaper Hamburger Abendblatt was launched, the first daily newspaper created by Axel Springer. 1950s The year 1952 saw the launch of the popular daily newspaper Bild. The paper was based on the British tabloid Daily Mirror, and peaked at circulation of 5 million in the 1980s. In 1953, Axel Springer Verlag bought the publishing house Die Welt, including the daily paper Die Welt and the Sunday paper Welt am Sonntag. In 1956, the company headquarters in Hamburg was built. Then in 1959, the company acquired the a holding in Ullstein AG, which owned Berlin newspapers Berliner Morgenpost and B.Z. and the Ullstein book-publishing business. 1960s The official opening of the Berlin headquarters took place in 1966. Hamburg remained an important site. After the attack on the student leader Rudi Dutschke on 11 April 1968, the APO (Extra-Parliamentary Opposition) began acts of violence against the company. The APO had a history of animosity with the Springer Group's allegedly biased coverage of the student movement. For instance, in the wake of the shooting of Benno Ohnesorg by the police at a student demonstration against the Shah, one Springer paper reported that "what happened yesterday in Berlin had nothing to do with politics …. It was criminal in the most sickening way." In fact, Ohnesorg, who had never attended a demonstration before, had been shot in the back while trying to leave the demonstration. 1970s The years 1972 and 1973 saw the building of the offset-printing plant in Essen-Kettwig. 1980s 1984 witnessed the official opening of the offset printing facility in Ahrensburg near Hamburg. In 1985, 49% of the company was offered for public subscription. Later that year Axel Springer died. Control was passed to his widow Friede Springer. In 1986, the first licensed edition of Auto Bild came out, in Italy. Other
