Nice compact history of US radio. Also lovely to trace a company history through several techs, phono->tape->radio->tv. And very interesting to hear about stolen lunches and ethical binds still relevant today. The invitation here (from the author, and submitter I presume) is to compare halcyon radio days with "AI". Not sure that works myself. The golden era of non-linear physics literally created fundamental new technologies each decade, By contrast "AI", blockchains etc are culmination advancements. The concluding remark is spot on IMHO. > it was unable to find a new source for dramatic growth. You wonder whether the same will be true of the Apples, Googles, Netflixes, Teslas and similar companies of the 2020s
