Erläuterungen zu diesen 1959er US-AUDIO Seiten

Die hier stehenden amerikanischen Artikel aus 1959 (aus der US-AUDIO) sind teilweise sehr gewöhnungsbedürftig, weil sie erstens aus einer längst vergangenen Zeit stammen und zweitens, weil dort in den USA ganz "anders" gedacht wurde als bei uns in Old Germany oder in Europa.
Vergleichbar mit unseren deutschen Hifi-Magazinen etwa ab 1962 ist jedoch, daß auch diese Zeitschrift ihre Anzeigen- Kunden und -Leser (be- oder ab- ?) werben mußte. - Weiterhin sind die Dimensionen des amerikanischen Kontinents mit den unseren hier in Europa nicht vergleichbar. - Ein Redaktions-"Trip" von New York nach Los Angeles oder gar in die Wüste nach Las-Vegas zu einer der Audio- "Shows" war - auch mit dem Flugzeug - immer noch eine Weltreise. Und jede Ausstellung oder "Messe" wurde als "Show" deklariert. Und natürlich, in USA musste alles "Show" sein, um beim Publikum einige Aufmerksamkeit zu erzeugen.

.

Was wußten die Hifi-Begeisterten und die Fachleute in 1959 ?

Damals wie auch Heute wurden neue Erkenntnisse relativ schnell veröffentlicht. In der US-AUDIO 1959 erschienen sporadische Listen von neuen Büchern, Heften und sonstigen Blättern, mal von den Verlagen, mal von den Herstellern. Nicht alle Ankündigungen waren Hifi- oder Stereo- bezogen, aber der US-AUDIO-Verlag brauchte auch interessante Neuigkeiten für seine Leser.
