A blog, also referred to as a weblog, is an informational site that consists of a single page of multiple entries known as posts that are displayed in reverse chronological order. The posts in a blog come from either one author or multiple authors dubbed as bloggers. Blogs often cover a single subject combining text, images, sometimes videos and links to other websites or blogs. Writing about a topic or event in a blog is known as blogging.
The different types of blogs include personal, group and organizational blogs. Some blogs cover a single subject, such as health, political, fashion, education, legal, music and beauty blogs. Some blogs such as vlogs comprise of videos and linklogs are blogs that comprise of links.
The first blog created was Link.net, and it was created in 1994 by a student of Swarthmore College called Justin Hall. In 1997, online diarist John Barger coined the term “weblog;” however, in 1999, Peter Merholz shortened the word to blog.
The rapid rise of blogs in the following years led to the invention of hosted blog tools such as Livejournal, Blogger.com and Open Diary. These tools are social media platforms that provide blog publishing services where users can write and publish their content online as well as share their thoughts and opinions with other bloggers.
