In 1997, Jorn Barger, blogger for Robot Wisdom, coined the term “weblog”, which was meant to describe his process for “logging the web” as he surfed the internet. The term “weblog” was shortened to “blog” in 1999, by programmer Peter Merholz.
In the early stages, a blog was a personal web log or journal in which someone could share information or their opinion on a variety of topics. The information was posted reverse chronologically, so the most recent post would appear first.
Nowadays, a blog is a regularly updated website or web page, and can either be used for personal use or to fulfill a business need.
