The blogosphere is a term that decribes the community of blogs and implies that blogs create a connected community or a social network of postings/information.
  • All blogs and their interconnections
  • It includes every blog available, and those who follow those blogs.
  • The term was coined on September 10, 1999 by Brad L. Graham, as a joke. It was re-coined in 2002 by William Quick, and was quickly adopted and propagated by the warblog community, the news of the ongoing war.
  • Works as a gauge for the public opinion
  • Cited in academic and non-academic work as evidence of rising and falling resistance to many political and world phenomena
  • Used to identify influential bloggers and "familiar strangers"
  • Tracked by Technorati, BlogPulse, Tailrank, and BlogScope websites.
  • Many news sources, such as CNN and the BBC, have used the term blogosphere several times to discuss public opinion, helping to give it a sense of legitimacy. It has been treated as a way to gauge public opinion about many topics, which is testament to the number of ways the Internet is changing things.
  • Levinson gives a small critique about the term "blogosphere" saying that while the term is used to discuss public opinion, we should be careful not to attribute all similar bloggers in the blogosphere to be the same. When the media reports things such as, "liberal bloggers are outraged," we need to understand that that may only be a few liberal bloggers out of hundreds that have made angry blog posts. It may be said that instances like that may lead to stereotyping or grouping all of a certain kind of blog together in an unfair or exaggerated way. Not all blogs in the blogosphere share the same sentiments.

"Blogosphere" is actually defined in the dictonary. On, "blogosphere" is defined as "a collective term for the world of weblogs, the community of all weblogs."
  • The term comes from the words "blog" (obviously) and "stratosphere."
