Some of the story of the Danish radio factories' path into television is inspired by the personal story of engineer Herman Høedholt. In the winter of 1950 he built a television as an experiment while working for the radio factory Linnet & Laursen. At the Copenhagen radio fair that same year his set was declared the best of the exhibited models. He later started his own television factory, Larsen & Høedholt, with an associate.
Technician Peter Hansen, who was among the people behind the development of Danish television, helped the filmmakers create an exact copy of the original studio facilities as they stood at Radiohuset, Copenhagen.

Episode 1.7: When Frøken Jørgensen exits Aage Haslund's room
she explains to Hr. Stoklund that Haslund works for 'Statsradiosofien'. The correct name is 'Statsradiofonien' - literally 'the State Radiophony'. Since Frøken Jørgensen is in a somewhat frisky mood at the time, it is not unlikely that the mistake was deliberate.
