Heidegger and Television

It is still a bit surprising that Heidegger, a major figure in philosophy of technology, didn't leave any systematic reflections on radio and television, even though he was obviously familiar with both of these technologies from the pre-WW2 era. The fact that mid-20 century media remained outside Heidegger's theoretical scope might indicate the presence of "modernist fundamentalism" (and it is the same modernism, which found a threatening dimension in the technologies of post-Industrial revolution). It's quite peculiar that at the end of his life he became interested in television after all... but only as a medium for broadcasting soccer games.
