Starting the journey – what is a blog?
Originally, blog was short for weblog. According to Wikipedia, the term weblog was first used in 1997, and people started using blogs globally in 1999. The terms weblog, web blogging, and weblogger were added to the Oxford English Dictionary in 2003, though these days most people leave off the we part.
Just to give you a more plain-English explanation, a blog is a website that usually contains regular entries made by an author. These entries can be of various types, such as commentary, descriptions of events, photos, videos, personal remarks, tutorials, case studies, long opinion pieces, political ideas, or whatever else you can imagine. They are usually displayed in reverse chronological order, with the most recent additions at the top. Those entries can be organized in a variety of ways, by date, topic, subject, and so on.
One of the main characteristics of a blog is that it's meant to be updated regularly. Unlike a website where the content is static, a blog behaves more like an online diary, wherein the blogger posts regular updates. Hence, blogs are dynamic with ever-changing content. A blog can be updated with new content and the old content can be changed or deleted at any time (although deleting content is not a common practice).
Most blogs focus their content on a particular subject, for example, current events, hobbies, niche topics, and technical expertise. This doesn't mean that blogs are meant to be published only by individuals sharing their personal opinions on given matters. On the contrary, these days, blogs have become a significant part in the online presence for many businesses and even corporations. The modern practice of content marketing is now one of the most widely accepted web marketing methods, and its core is based on publishing quality content, often in blog form.
