Notice in the second paragraph how Brecht's vision for radio better matches the internet, more specifically web 2.0 technology, which he could never have imagined in 1932, but sorta does.
The Radio as an Apparatus
by Bertolt Brecht; July 1932
In our society one can invent and perfect discoveries that still have to conquer their market and justify their existence; in other words discoveries that have not been called for. Thus there was a moment when technology was advanced enough to produce the radio and society was not yet advanced enough to accept it. The radio was then in its first phase of being a substitute: a substitute for theatre, opera, concerts, lectures, cafe music, local newspapers and so forth. This was the patient's period of halcyon youth. I am not sure if it is finished yet, but if so then this stripling who needed no certificate of competence to be born will have to start looking retrospectively for an object in life. Just as a man will begin asking at a certain age, when his first innocence has been lost, what he is supposed to be doing in the world.
...As for the radio's object, I don't think it can consist simply in prettifying public life. Nor is radio in my view an adequate means of bringing back cosiness to the home and making family life bearable again. But quite apart from the dubiousness of its functions, radio is one-sided when it should be two-. It is purely an apparatus for distribution, for mere sharing out. So here is a positive suggestion: change this apparatus over from distribution to communication. The radio would be the finest possible communication apparatus in public life, a vast network of pipes. That is to say, it would be if it knew how to receive as well as to transmit, how to let the listener speak as well as hear, how to bring him into a relationship instead of isolating him. On this principle the radio should step out of the supply business and organize its listeners as suppliers. Any attempt by the radio to give a truly public character to public occasions is a step in the right direction.
...Whatever the radio sets out to do it must strive to combat that lack of consequences which makes such asses of almost all our public institutions. We have a literature without consequences, which not only itself sets out to lead nowhere, but does all it can to neutralize its readers by depicting each object and situation stripped of the consequences to which they lead. We have educational establishments without consequences, working frantically to hand on an education that leads nowhere and has come from nothing.
...The slightest advance in this direction is bound to succeed far more spectacularly than any performance of a culinary kind. As for the technique that needs to be developed for all such operations, it must follow the prime objective of turning the audience not only into pupils but into teachers. It is the radio's formal task to give these educational operations an interesting turn, i.e. to ensure that these interests interest people. Such an attempt by the radio to put its instruction into an artistic form would link up with the efforts of modern artists to give art an instructive character. As an example or model of the exercises possible along these lines let me repeat the explanation of Der Flug der Lindberghs that I gave at the Baden-Baden music festival of 1929.
