The word “blog” is a shortened form of the term “weblog,” which was coined by Jorn Barger on December 17, 1997. The shorter version “blog” was coined by Peter Merholz, who jokingly broke the word “weblog” into the phrase “we blog” in the sidebar of his blog Peterme.com in April or May 1999.

The term “weblog” itself originated from the practice of logging or recording information on the web, similar to how sailors would log details of their voyages in a ship’s log. The “web” part refers to the World Wide Web, and “log” refers to the act of recording or journaling.

So in essence, “blogging” stems from the concept of maintaining an online log or journal, which evolved from earlier forms of digital communities like Usenet, email lists, and bulletin board systems. The term gained widespread popularity after Pyra Labs used “blog” as both a noun and verb in connection with their Blogger product in the late 1990s.
