If you have a few hours to kill, the Youtube Channel "Another Boring Topic" has a multi part series on the "rise and fall of the IBM PC". The comparatively short Part 1 is here: https://www.youtube.com/watch?v=Er8wcWsG7sE

The Channel has similar video series on OS/2, VisiCalc, Microsoft Excel and early Windows (far from completion). The videos are generally very detailed and well researched, often contrasting accounts from different source or even reaching out to people involved.

The already slow pace of the channel has slowed down a lot. In an update video a while back, the author has announced that the background research for the IBM PC led down an unexpectedly deep rabbit hole and his script eventually spiraled into an unfinished book that will now probably turn into a two-parter itself.
