Links.net and Scripting.com were blogs before the term existed. And Movable Type, Greymatter, and numerous other blogging tools existed long before WordPress, which was relatively late to the game (and technically a fork of a prior project).
Nowadays, we also have more modern tools like Jekyll, Ghost or whatever for blogging.
Blogging predates all blogging services, platforms, and software. Blogging was invented by early web pioneers. The corporations followed in the Gold Rush of the 1990s dot-com bubble, and they've been trying to monetize our social lives ever since.
Nowadays, thanks to marketing machines and television talking heads, nobody has "websites" anymore, we have "blogs".
while not blog "software", one could say that the contents of an html directory exposed by, for example, http://weirdmachinehostname.university.edu/~username/ were the earliest blogs. Hand crafted HTML homepages and such.
Hmm nah, I remember “blogging” explicitly meant drafting and publishing posts directly from a website form, as opposed to crafting HTML documents and uploading them over FTP (which was what people did at the time and obviously complained about.)
The word "blog" appeared a few months before the infrastructure to draft and publish posts directly from a website form. And the concept of diaries/weblogs that it designated was a few years older.
Whilst not an open blog platform, CmdrTaco of Slashdot claims his Slashdot prototype 'Chips and Dips' which he created in 1997, was one of the first 'blogs'.
Didn't blogging start on wordpress/blogger/livejournal?
