57、r to much of what we hear on the radio today in that de forest played only music. but because there were still no home radio receivers, de forests audience consisted of only wireless operators on ships in new york harbor. there is no doubt that radio broadcasting was quite a novelty in those days. b

58、ut it took a while to catch on commercially. why? for the simple fact that only a few people, in fact, only those who tinkered with wireless telegraphs as a hobby, owned receivers. it wasnt until the 1920s that someone envisioned mass appeal for radio. this was radio pioneer, david sarnoff, who pred
