Jorn Barger created the first blog, which he called a "weblog", in 1997 as a novel form of web publishing. A blog is a collection of private or public thoughts that are regularly added to and displayed in reverse chronological order. Blogging involves making posts to a web log or blog, while comments are written explanations, criticisms, or illustrations that are added to textual materials. Blogs can be used to share news and debates, support claims, or simply have fun, and aim to engage both genders across a wide age range.
