In einem Buch aus 1962 haben wir es gefunden

Wie denken die Engländer im Jahr 1962 über die Meilensteine der Audio-Technik ? Von den Amerikanern (also in einem Buch aus Amerika) haben wir gelesen, daß fast alle markanten Erfindungen in den USA stattfanden, vor allem, das Magentbandgerät wurde von AMPEX erfunden usw....... In dem ganzen amerikanischen Buch kommt der Begriff "Europa" nur am Rande vor, das sei eine Insel draußen vor Neupfundland. Nun ja .....

Diese englische Auflistung sieht also recht neutral und ausgewogen aus.

Natürlich sehen Engländer die Audio-, Tonband- und Hifi Welt aus ihrer Sicht (dem Kernland des Empire) etwas anders als wir hier in Deutschland West. Denn auch bei uns ist immer noch nicht alles aus den verdammten 12 Jahren korrekt aufgearbeitet, zum Bespiel die Legenden um den alten Paul Nipkow, der ja das Fernsehen erfunden haben soll, laut NS Propaganda im Dritten Reich - sowie die Legenden um Walter Bruch, der ja das Farbfernsehen erfunden haben soll. Im Fernsehmuseum können Sie lesen, was es damit wirklich auf sich hatte.
