Internationale Funkausstellung Berlin

The IFA or Internationale Funkausstellung Berlin (International radio exhibition Berlin, a.k.a. 'Berlin Radio Show') is one of the oldest industrial exhibitions in Germany. Between 1924 and 1939 it was an annual event, but as from 1950 it was organized on a two yearly basis until 2005. Since then it has become an annual event again, held in September. Today it is one of world's leading trade shows for consumer electronics and home appliances.

It offers the opportunity to exhibitors to present their latest products and developments to the general public. As a result of daily reporting in almost all the German media, the radio exhibition achieves a large spreading of the information – and advertising messages and has also become international. In the course of its history, a large number of world innovations were first seen at the exhibition.

As of 2015^[update] IFA is “Europe’s biggest tech show”. 245,000 visitors and 1,645 exhibitors attended IFA 2015.

German physicist and inventor Manfred von Ardenne gave a public demonstration of a television system using a cathode ray tube for both transmission (using flying-spot image scans, not a camera) and reception, at the 1931 show.

In 1933 The Volksempfänger (VE 301 W), a Nazi-sponsored radio receiver design, was introduced. Ordered by Dr. Joseph Goebbels, designed by Otto Griessing, sold by Gustav Seibt, it was presented at the tenth Berliner Funkausstellung on 18 August 1933, its price fixed at 76 Reichsmark (RM). 100,000 units were sold during the exhibition.

In 1938 the DKE 38 (Deutscher Kleinempfänger 38, i.e. German miniature receiver 1938) followed, the price fixed at 35 RM.
