Who owns Blogspot?

I'm trying to confirm something and would appreciate help: who currently owns Blogspot (the platform many people still refer to as Blogspot or Blogger)?

I've seen references to Google and to Blogger, but I'm not certain whether the ownership or branding has changed recently — can anyone clarify the current owner and relationship between Blogspot and Blogger?

Also curious: has the service been sold, merged, or rebranded at any point that would affect who controls it today?

If you know, please explain briefly — what company manages the platform, and where can I find official confirmation?

Thanks in advance for any clear, up-to-date answers — I'm asking because I want to cite the correct owner in an article.
