I enjoy reading about the history of personal computers and the internet. Especially the period of 80th and 90th. As it's the history of the industry, there is a lot to learn from it. What kind of ideas are working and what aren't? What makes a software product successful? What makes a software team successful? And what could be the fastest ways to fail? Etc..
And recently I was listening to an interview with the creator of Internet History podcast. And just going throw the list of episodes the topics are quite impressive. Check it out.
P.S. You can find it in any podcast app.
