According to Wikipedia, Blogosphere is the collective term encompassing all weblogs or blogs as a community or social network. Many blogs are densely interconnected. Bloggers read each other’s blogs, create links to them, refer to them in their own writing, and post comments on each other’s blogs. Because of this, interconnected blogs have created their own culture.
While a blog tries simply to present content, using resources such as text, images, videos, etc., the Blogosphere is a collective term whose aim is to encompass all blogs as a community or social network. In this way, the term can be considered a social phenomenon.
