Blogging refers to writing, photography, and other media that's self-published online. Blogging started as an opportunity for individuals to write diary-style entries, but it has since been incorporated into websites for many businesses.

“Blog” is an abbreviated version of “weblog,” which is a term used to describe websites that maintain an ongoing chronicle of information. A blog features diary-type commentary and links to articles on other websites, usually presented as a list of entries in reverse chronological order. Blogs range from the personal to the political, and can focus on one narrow subject or a whole range of subjects.
