> Spark gap transmitter were (one of?) the first form of radio broadcasting AFAIK this is also the reason the German language uses the word funken for transmitting wireless broadcasts, derived from Funke (spark). And of course the corresponding noun Funk, often embedded in typical, lengthy noun constructs. The German company Telefunken also has a couple mentions in the Wikipedia article you linked to, as one of the early manufacturer of commercial radio equipment.
