Ask HN: Stories of Platforms Getting Dethroned?

I think recently there was here an article about a phenomenon called after a Roman defeat by Hannibal, which described how companies lost there competitive advantages by being overly confident in there successful business. There were example with Kodak loosing to upcoming video technology, or DEC loosing market by personal computer getting more & more popular. Even after searching for a while I kind find that article. It would fit here because it has could examples.

Would encourage not thinking of it as dethroning or winner take all. There are new niches and subpopulations developing all the time. Tiktok developed a new niche from Youtube but Youtube still growing. Bluesky taking share from Twitter but Twitter still very large. AI will help more disruption occur from smaller higher leverage teams.

Was common in the 90s and 2000s. OS&#x2F;2, Sun, RealPlayer, IE, ActiveX, Java applets, Netscape, Yahoo, Lycos, Altavista, Blackberry, Nokia, PalmPilot, Angular, AIM, ICQ, MySpace, MS Office, Skype, the desktop operating system in general, .Net, IRC..<p>And these days, Zoom seems to have given way to Teams and Meet. Slack lost to Discord. Facebook to Insta (though Meta just bought them), YouTube to TikTok, etc.
