The Oxford English Dictionary Online defines the noun blog as, “2. A frequently updated web
site consisting of personal observations, excerpts from other sources, etc., typically run by a
single person, and usually with hyperlinks to other sites; an online journal or diary.” On the
Internet, a blog is a personal or professional journal that is frequently updated and intended for
general public consumption. The essential characteristics of the blog are its journal form,
typically a new entry each day, and its informal style. Many blogs include photo, audio, and
video information.
