1. Blogging means writing for a blog. Its does not requires any writing skill or exprtise. Anyone subscribed to
a blog can write for it expressing their views.
Now a blog (a portmanteau of the term web log)[1] is a personal journal published on the World Wide
Web consisting of discrete entries ("posts") typically displayed in reverse chronological order so the most
recent post appears first. Blogs are usually the work of a single individual, occasionally of a small group,
and often are themed on a single subject. Blog can also be used as a verb, meaning to maintain or add
content to a blog.
The emergence and growth of blogs in the late 1990s coincided with the advent of web publishing
tools that facilitated the posting of content by non-technical users. (Previously a knowledge of such
technologies as HTML and FTP had been required to publish content on the Web.)
Although not a must, most good quality blogs are interactive, allowing visitors to leave comments and
even message each other via GUI widgets on the blogs and it is this interactivity that distinguishes them
from other static websites.[2] In that sense, blogging can be seen as a form of social networking. Indeed,
bloggers do not only produce content to post on their blogs but also build social relations with their
readers and other bloggers.[3]
FUNCTIONS:
commentary on a particular subject;
function as personal online diaries;
online brand advertising of a particular individual or company.
CONTENT:
A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its
topic. The ability of readers to leave comments in an interactive format is an important part of many blogs.
Most blogs are primarily textual, although some focus on art (art blog), photographs (photoblog), videos
(video blogging or vlogging), music (MP3 blog), and audio (podcasting). Microblogging is another type of
blogging, featuring very short posts.
As of 16 February 2011, there were over 156 million public blogs in existence.[4]
Types
There are many different types of blogs, differing not only in the type of content, but also in the way that
content is delivered or written.
Personal blogs
The personal blog, an ongoing diary or commentary by an individual, is the traditional, most
common blog. Personal bloggers usually take pride in their blog posts, even if their blog is never
read. Blogs often become more than a way to just communicate; they become a way to reflect on
life, or works of art. Blogging can have a sentimental quality. Few personal blogs rise to fame and
the mainstream but some personal blogs quickly garner an extensive following. One type of
personal blog, referred to as a microblog, is extremely detailed and seeks to capture a moment in

2. time. Some sites, such as Twitter, allow bloggers to share thoughts and feelings instantaneously
with friends and family, and are much faster than emailing or writing.
Corporate and organizational blogs
A blog can be private, as in most cases, or it can be for business purposes. Blogs used internally
to enhance the communication and culture in a corporation or externally
for marketing, branding or public relations purposes are calledcorporate blogs. Similar blogs for
clubs and societies are called club blogs, group blogs, or by similar names; typical use is to
inform members and other interested parties of club and member activities.
By genre
Some blogs focus on a particular subject, such as political blogs, travel blogs (also known
as travelogs), gardening blogs, house blogs,[23][24] fashion blogs, project blogs, education
blogs, niche blogs, classical music blogs, quizzing blogs and legal blogs (often referred to as a
blawgs) or dreamlogs. Two common types of genre blogs are art blogs and music blogs. A blog
featuring discussions especially about home and family is not uncommonly called a mom blogand
one made popular is by Erica Diamond who created Womenonthefence.com which is syndicated
to over two million readers monthly.[25][26][27][28][29][30] While not a legitimate type of blog, one used
for the sole purpose of spamming is known as a Splog.
By media type
A blog comprising videos is called a vlog, one comprising links is called a linklog, a site containing
a portfolio of sketches is called a sketchblog or one comprising photos is called
a photoblog.[31] Blogs with shorter posts and mixed media types are called tumblelogs. Blogs that
are written on typewriters and then scanned are called typecast or typecast blogs;
see typecasting (blogging).
A rare type of blog hosted on the Gopher Protocol is known as a Phlog.
By device
Blogs can also be defined by which type of device is used to compose it. A blog written by
a mobile device like a mobile phone or PDA could be called a moblog.[32] One early blog was
Wearable Wireless Webcam, an online shared diary of a person's personal life combining text,
video, and pictures transmitted live from a wearable computer and EyeTap device to a web site.
This practice of semi-automated blogging with live video together with text was referred to
assousveillance. Such journals have been used as evidence in legal matters. [citation needed]
Reverse blog
A Reverse Blog is composed by its users rather than a single blogger. This system has the
characteristics of a blog, and the writing of several authors. These can be written by several
contributing authors on a topic, or opened up for anyone to write. There is typically some limit to
the number of entries to keep it from operating like a Web Forum.

3. Viral marketing, viral advertising, or marketing buzz are buzzwords referring to marketing techniques
that use pre-existing social networks to produce increases in brand awareness or to achieve other
marketing objectives (such as product sales) through self-replicating viral processes, analogous to the
spread of viruses or computer viruses (cf. memes and memetics). It can be delivered by word of mouth or
enhanced by the network effects of the Internet.[1] Viral marketing may take the form of video clips,
interactive Flash games, advergames, ebooks, brandable software, images, or text messages.
The ultimate goal of marketers interested in creating successful viral marketing programs is to create viral
messages that appeal to individuals with high social networking potential (SNP) and that have a high
probability of being presented and spread by these individuals and their competitors in their
communications with others in a short period of time.
The term "viral marketing" has also been used pejoratively to refer to stealth marketing campaigns—the
unscrupulous use of astroturfing online combined with undermarket advertising[clarification needed] in shopping
centers to create the impression of spontaneous word of mouth enthusiasm.[2]
