A typical blog is an information hub comprising of text, images and weblinks related to other web pages and blogs, along with other media related to the topic.



Meanwhile, in layman language, a blog is essentially defined as a frequent, chronological publication of personal thoughts and web links.

The act of authoring and maintaining a blog, or adding an article to an existing blog is known as blogging. Individual articles on a blog are referred to as blog posts or entries and the person who posts these entries is called a blogger.

History

The pre-digital electronic community witnessed many forms of electronic communications including the likes of wire fights of AP wire, usenet, e-mail lists and bulletin board systems (BBS), going on to threads, the running conversations created by WebEx.

The concept of a blog as we know it today evolved from the system of online diaries where people would keep a running account of their personal lives. The term weblog was coined in 1997 by Jorn Barger and abridged to blog by Peter Merholz.

Functions

A blog has one or more of the following functions to perform:

To focus on a particular subject, such as food, politics, news etc.

Role of Blogs

Blogs have come to play an important role which benefits the community on a whole. Here we????????ve discussed a few of them:

Information dissemination

Many times, bloggers have to their credit leading the way in bringing key information to public light and breaking and shaping news stories. This leaves the mainstream media with the task of reacting to this news, instead of it being vice-versa. One of the major instances is the furor created by the blogs of the left-swing and right-swing bloggers during the Iraq war.

Mobilising public opinion

Blogs have played a major role in bringing the common mans opinion to the forefront and raising the magnitude of its effectiveness and influence. The incident in year 2002 when the U.S. Senates Majority Leader Tent Lotts infamous comments carrying a tinge of racial segregation were brought to the limelight by the onslaught of bloggers is a major example. Lott was eventually forced to step down owing to the public pressure built this way.

Public Contact

Blogs have also come to act as a major link between the politicians and leaders and the general public. Blogs are increasingly used by these leaders to express their opinion on wars and other issues, acting as major contact between them and the common man. This has made blogging an important tool for outreach and opinion forming.
