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 from 1950 it was held every other year 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.
