It turns out ANTIC interviews quite a few people from the old computer magazine and book industry, and retronauts is mostly made up of struggling video game journalists who cycle between the same magazines and being jobless or freelance. A few of them, especially the more senior folks basically have thrown in the towel and now work for other companies entirely within the video games industry.
What's really interesting about the ANTIC interviews is how close those folks were to the thing that basically displaced them (computers and ubiquitous networking), and yet none of them seems to have predicted it happening. To them the publishing and periodical industries had always been there and always will be. Their own employer going out of business was more due to local market forces affecting them or mergers between companies.
For the record, it didn't occur to me either. In the mid 90s I was sitting next to an incoming T-1 line at a startup ISP sending off physical envelopes with job applications to gaming and computer magazines I enjoyed hoping to become a journalist myself. One of the magazines that did reply (by mail btw) went out of business itself about 6 years later.
