IFA Trade Show Girls, Berlin, Germany

In 1939 the exhibition was called Grosse Deutsche Funk- und Fernseh-Ausstellung (Great German Radio and Television Exhibition). The Einheits-Fernseh-Empfänger E1, a TV set designed to be affordable for everybody, was introduced. The physical display size was 7.68" × 8.86". Plans for large-scale manufacture were thwarted by the outbreak of WWII. Color TV was also introduced (a prototype), based on an invention by Werner Flechsig (cf. shadow mask).
Multinational Dutch electronics corporation Philips introduced the compact audio cassette medium for audio storage at the 1962 show.
