Heise Group
German media conglomerate
Heise Gruppe GmbH & Co. KG is a German media conglomerate headquartered in Hanover. It was founded in 1949 by Heinz Heise and is still family-owned. Its core business is directory media as well as general-interest and specialist media from the fields of computer technology, information technology and network culture. Another focus of its business activities is portals for price and product comparisons.
History
In 1949, Heinz Heise founded the publishing house named after him in Hanover-Badenstedt. The company's first product was an address book for the town of Bünde, later joined by the telephone directory for Einbeck. Gradually, other cities and regions were added to the product range. In addition, Heise expanded the program to include non-fiction topics, such as manuals on law. By 1960, sales had risen to over one million marks.
Begin with the source’s own compact description: “Heise Group” is german media conglomerate. The dossier treats that line as a proposition to test through Heise, Group and German, not as a finished interpretation.
Why this record matters
The phrase “german media conglomerate” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q896769. VIAF identifies the subject as 313438636. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1949 and 1960.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
