A blog is a website or web page that is regularly updated by an individual or a small group. Usually written in an informal or conversational style, blogs contain online personal reflections, comments and often hyperlinks provided by the author(s). Blogging is a fairly recent phenomenon, having come into existence with the advent of the internet. The first known use of the term “blog” was as a contraction of “web log” in 1999. Blog entries vary in length and content. Blogs can serve a number of purposes. Some are written for purely personal reasons, others are produced by businesses, corporations and institutions to market themselves or a particular idea. Bloggers can have a strong following, or readership. Some individuals make their living by blogging, using the opportunities it affords to work independent of location from anywhere in the world.
