I can only think of a few other companies that manage this feat. Nintendo's history seems to be rather frequently circulated (and I don't follow video gaming blogs, though I do occasionally play their games). Intel, Compaq, and IBM also see historical items published, but it's mostly concerning events that predate the 90's, a time when these companies were either much more visible or had a more prominent role. I've not seen much published about the past two decades of history for any other tech company at the same level as Apple.
The histories of other companies seem to be given a much more technical treatment: hardware schematics, design constraints, sourcing problems, blow-by-blow accounts, etc. That might just be because many of the Apple anecdotes are published as "fluff" for non-technologists; Apple also sees its share of technical history published, too.
Maybe I'm just blind to everything else or I'm biased in a particular way, but it certainly feels like we're telling a particular narrative here. If I were a future historian looking back, this might cloud my perspective. Everything seems to be about Apple. Am I wrong?
