You're welcome. Reading the old electronics magazines is a great way to study history. There are a number of sites with many titles to read. You can start with the beginning of commercial radio broadcasting in 1920 and see electronics circuits as they evolve. You read about all the problems that had to be solved for broadcasting to be successful and the difficulties that existed in finding a successful business model. In the beginning advertising on radio was considered to be a big no-no.
In the early days RCA tried to monopolize all aspects of radio from broadcasting, to tubes, to radio manufacture, to print media regarding radio. Check inside any radio from the 1920s to 1930s and there is probably a label with a huge list of patents it was built under.
The evolution of television is also covered which literally took decades of really stupid concepts before someone decided to use a CRT to display the picture. The CRT was around for at least a decade before someone hit on the idea to use it.
You also get an entirely different perspective on WWI, the depression, WW2 and so on. You will read things that you'll never see in a history book.
