Ah, that is actually a good question!

I think I can start with a quote from wikipedia:

“A blog (a blend of the term web log) 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.” If you would like too, you can read more here.

People started to realize other useful use of blogs rather than publish a personal journal! 

So, they developed the idea as we see it today, blogs can be used for fun, and also for business and many other purposes, it’s even more powerful tool if used in the Media!

I remember that the Media coverage of the Iraq War was actually done by bloggers who was in the middle of the event, so there were no way for journalists to enter that time, this is how the idea of “citizen journalist” came out after that and changed the whole thing!

@arnizophoniasson Hi Arni!  I usually define a blog as regularly updated with the ability to add discussion.  Some sites have “blogs” which are really just news streams where they publish announcements, but there is no interaction.  I think the interaction portion is really what defines a blog!
