Blog is the short form of the word "weblog" and a blog is just another type of website that is simple, easy to use and is updated on a frequent basis. However, what makes a blog different from a normal site is that the items appear in reverse chronological order. This means that the latest item appears at the top of the list whereas the oldest either appears at the bottom of the list or resides in an archive section on the blog. This necessitates the need of specific blogging software which is only offered by blog web hosting companies. Blogs are usually maintained by individuals as opposed to usual websites which may be administered either by individuals or by large enterprises.

The items appearing on a blog are referred to as posts and may comprise a mixture of a variety of data including text, images as well as multimedia items. Each item has a date and time associated with it. In other words, a blog can also be called as an online journal with a list of publications appearing in the reverse order. Posting a new blog item is as easy as 1-2-3 and can be done by filling out a simple form and clicking the "Post" button.

Blogs are a major divergence from the 20th century information communication approach in which news companies with a select group of people were responsible for collecting and publishing certain news items. This has changed in the 21st century in which anyone with a blog can post news items on almost any topic ranging from sports, music, history, politics etc.

It is common for a blog to have a comments input section at the end for the users to give their views on the latest items posted. The feedback on posts results in a significant interaction between the bloggers setting up a kind of bloggers' community. All the web hosting providers listed at AWHD offer blog web hosting which means that the blogging software is included for free in their hosting plans.
