Yahoo Japan is actually a completely separate company.

Yahoo itself is still extremely popular in the US, just with a different demographic than we (the sort of people on the fediverse) regularly interact with. Their sports, finance, and news sites are some of the most popular on the internet. I don’t think it’s particularly relevant in the web search space these days though, and hasn’t been for a long time.

I think we don’t hear much about it because it has found a niche and is staying within it. It’s profitable, but not on an “infinite growth forever” trajectory so it rarely makes the news. Honestly kind of respectable.
