Word Origin & History

1998, short for weblog (which is attested from 1994, though not in the sense 'online journal'), from (World Wide) Web + log. Joe Bloggs (c.1969) was British slang for "any hypothetical person" (cf. U.S. equivalent Joe Blow); earlier it meant "a servant
boy" in one of the college houses (c.1860, see Partridge, who describes this use as a "perversion of bloke"), and, as a verb, "to defeat" in schoolboy slang. The Blogger online publishing service was launched in 1999.

online journal where an individual, group, or corporation presents a record of activities, thoughts, or beliefs. Some blogs operate mainly as news filters, collecting various online sources and adding short comments and Internet links. Other blogs concentrate on presenting original material. In addition, many blogs provide a forum to allow visitors to leave comments and interact with the publisher. "To blog" is the act of composing material for a blog. Materials are largely written, but pictures, audio, and videos are important elements of many blogs. The "blogosphere" is the online universe of blogs.
