I'm not sure anyone else really qualifies as a big very consumer-facing tech company in the modern sense from that era or before though, of course, there were many once popular companies like MySpace that just flamed out. Yahoo! might be an example.
I know they’ve changed their tune on open source but it’s really hard for me to break from my 20+-year perception that they are the evil company that makes awful software.
The only thing that was ever revered about them was Bill Gates, who was more loved by business schools as a case study in how to run an extremely aggressive company.
Terminals connected to minicomputers--which is what I used at work through most of that period? DOS-based word processing and spreadsheets were pretty nice by comparson.
Macs? They were fine in the mid-80s although I didn't use them in school unless my group was using them for some project.
Unix workstations were getting pretty nice by the mid-90s but those weren't something for a home user.
But expectations were much lower then, computers were expected to be a thing for a 'hobbyist' to tinker with, and those who did generally did it because they loved it.
(I still don't think what were then called "PCs" running MS-DOS or (beginning in 1985) Windows were as beloved as Amiga or Commodore 64 though, Microsoft-OS PCs were for "business", and nobody really loved them).
(Macintosh was first sold in 1984, so mid-80s was the first Macintosh).
OTOH Microsoft software's operation experience was far from happy. Bugs, crashes, byzantine installation and update procedures were all the daily reality.
To say the truth, few things were significantly better. And if they were (say, VMS, which was rock solid), they were also significantly more expensive.
Commercial Unix wasn't a hugely better; I personally crashed Solaris software, and the OS proper once. Bizarre installation and update procedures applied to it equally well.
MS started having a hit after a hit to its reputation in the tech community when it started to try to do something about the internet. They tried to muck with Web technologies so as to create its own silo, not compatible with Netscape's: custom HTML and CSS, JScript vs Javascript, etc. They also started to talk trash about competition, never a good sign. Eventually they won, partly via business pressure, partly via good technology, and many a web developer cursed the MSIE5 chokehold since then, for a decade at least.
Windows 95 was a target of many techie jokes, but, to my mind, MS have done a tremendously successful rework of desktop experience and its visual language, which was and still is widely emulated as "the common standard". Writing an OS as a DOS extender was a cool hack, which allowed to launch DirectX, and make windows a prime gaming platform.
It was truly amazing. MSDN on CDs.
It's a little embarrassing to think about right now when you realize that Microsoft has never poisoned a river or sent thugs with billy clubs to bust a union, and so all of us had bigger fish to fry. But there was never love.
Microsoft represented an existential threat to many, many parts of the IT ecosystem every bit as real as dumping toxic waste into salmon breeding grounds.
MS is like a boxer who doesn’t just want to beat you in the ring. He wants to outright kill you too so you will never fight again.
They were very beloved, back when they were a scrappy upstart in the 1970s.
It may have certainly been friendly to a lot of users, yet it did not ring friendly to a lot of useful content.
Then also comes the geo segmentation. There was a time when quite a few results would be from foreign language sites or other countries. Sure, it created noise when the language was very much foreign, though later there often was a link to Google? translate.
I guess there may still be a way to have all that in the mix, but, generally the results are being streamlined.
Repeat once per generation, to infinity
And then some PE vultures do a hostile takeover and we're back to step 1.
Happened to the Greeks, the Roman Empire, Imperial China, the British Empire, IBM, Intel and AMD back and forth, Toyota, Boeing, Yahoo, Google, MySpace, Facebook...
Also presumably soon to happen for the United States, Nvidia, Mysterious Twitter X, TSMC, and others currently reigning as kings in their respective corners of the world.
Note that falling doesn't mean they will disappear into the history books, but they will all fall sooner or later.
If an entity wants to stick around into perpetuity, never go higher than #2 and maybe never go higher than #3 so when #1 falls you don't end up becoming the new #1 out of nowhere.
