While thinking about what to blog about the word sounded funny to me. I thought where did that word come from and when and where did blogging come from. This led me to our good friend Google :)
The term BLOG is short for WebLog, The term was adopted in 1999 to say "We Blog" however blogging has been around since the early 90's, they were originally single owners to hold self though discussions or instructional sites.
The term 'Blog' is the evolved term coined by Peter Merholz in 1999.
It's not an acronym,...it's a colloquialism. It comes from the conjoined terms web and log...as in weblog. Then it evolved into simply blog when Peter Merholz coined the term in 1999.
Today there are Multi-Author-Blogs or MABs and blogging is used around the world for many reasons.
