Maybe it is unfair to say “there was a time when more jazz was featured on TV”. I would not really know, because I stopped watching TV a while ago. Of course here in switzerland there is still some jazz on the public TV, late at night at some time.
But in the 1980s there was still some jazz to be seen and witnessed by people who did not expect to be treated with jazz when they turned on the TV. There were some broadcasts on swiss TV which you could say were in some kind of “magazine” format. Maybe some news from different regions, a talkshow guest, a funny report — you get the picture. At the end they always had a short slot for musical artists of every genre that happened to be in Switzerland – just a few minutes to promote their tour.
My friend, the late jazz researcher Otto Flückiger, must have scanned the TV program magazines every week to see if an interesting (interesting to him that is) band or musician would appear – since he managed to tape quite a lot of this jazz, blues and soul bits. I am offering you a little potpourri here of different things you could see – if you were aware when and where to look.
