     33        <p>Broadcasting was launched in Germany in 1923, being the third country in
     34           the world (right after the USA (1921) and Great Britain (1922)). From the
     35           technical point, it even would have been possible to launch large-scale

     48        <p>Detectors are passive tuners which are powered straight from the electromagnetic
     49           wave which is recieved via a very big antenna. Therefore there was only a
     50           headphones plug and no loudspeakers at all. To adjust the device, the user had
     51           to poke with a small needle on a crystal, having only a small chance to recieve
     52           a powerful broadcast station. The crystal was a small 5&nbsp;mm galena or pyrite
     53           unit with physical characteristics of a diode at some special configurations.
     54           If the user found such a configuration, the crystal served as rectifier.
     55           In the early 1920s, this setup was a cheap alternative to the expansive radio sets.
     56           At the right hand in the picture you can see a typical manual to instruct
     57           the user into early radio technology.</p>
     58           
     59        <p>It is astonishing to see the incredible speed of the development of broadcasting
     60           systems. Beginning with very simple devices like the one above, using crystals
     61           for demulation, the technology became mature very quickly. This process took
     62           no more than 15 years from the first steps to near perfection.
     63           This development is reflected in the apperance of the devices as well. While
     64           the first recievers were of a very technical design, later devices turned into
     65           wonderful pieces of furniture, fitting neatly into the average upper class
     66           household. We have illustrated this page with examples from both types of
     67           devices.</p>

     243                        and optionally battery driven, and of course since it is as compact as
     244                        carry-on-baggage. It even features an integrated recordplayer - forseeing the
     245            development of modern multipurpose receiver/CD-player combinations.
