Growth from 1950 to 1984

By the late 1950s the "office equipment industry" (as it was then called) already ranked as the third largest exhibitor group at HANNOVER MESSE. The Fair reflected the "electronics boom" in the 1960s and provided the launching pad for numerous technological highlights. In 1965, for example, Heinz Nixdorf (who was later to become one of Germany's best known entrepreneurs) presented his legendary 820 universal computer.

In 1970 Deutsche Messe underscored the importance of office equipment at HANNOVER MESSE when it opened the new Hall 1 adjacent to the northern entrance of the exhibition site. This massive building complex consisted of three levels: an underground garage with parking space for 2,000 exhibitors, a ground-floor exhibition hall covering a total area of 70,300 square meters, and a roof level with 750 prefabricated business suites. In 1984 Hall 1 found its way into the Guinness Book of Records as the "world's largest single-storey exhibition hall".
