In the early 1970s, GN is partly a telegraph company and partly a holding company. Almost all employees at the headquarters were telegraph staff.

The British cable producer, Submarine Cables, Ltd. delivers the world's so far longest submarine coaxial cable (570 km between Denmark and the UK) to GN. GN's annual income from the cable connections consequently rises from around DKK 7-8 million in the late 1940s to around DKK 15 million in the 1950s


In the summer of 1947, GN's managing director, Bent Suenson, receives an unexpected but important visit by two young engineers. They suggest that GN should become involved in a new prospering industry - FM radio communication.
