Matt Alt announced his forthcoming book: https://www.penguinrandomhouse.com/books/609076/pure-invention-by-matt-alt/ I strongly recommend that Skullbrainers pre-order the book, there will be some material in there that is relevant to your interests.
The book is being released tomorrow, here's a little discussion about it between Matt Alt and Patrick Macias:
About 80 pages in and it’s awesome so far. Tons of info I did not know. Some really mind blowing facts too. We should have a spoiler convo when people finish it.
Mat Alt has an article in the New Yorker about the walkman (maybe an abridged chapter from his book?) https://www.newyorker.com/culture/cultural-comment/the-walkman-forty-years-on
This is pretty cool, PBS referenced the book in this YouTube video about Pokemon, but pay particular attention at 5:25:
