Technorati has started releasing the State of the Blogoshpere 2008 report. It will be a couple of more days before the full report is online.
The previous report was release in April 2007, so a lot has changed in the past year-and-a-half. Here are just some of the highlights:
Blogs are now a pervasive part of our daily lives. While there have been a number of studies conducted that tried to understanding the size of the Blogosphere -- both in terms of the number of blogs and blog readership -- all of these studies agree that blogs are now a global phenomenon that is "mainstream."
Technorati cites the numbers from three of the studies, which vary in the details but generally agree that "blogs are here to stay."
comScore MediaMetrix (August 2008)
o Blogs: 77.7 million unique visitors in the US
o Total internet audience 188.9 million
eMarketer (May 2008)
o 94.1 million US blog readers in 2007 (50% of Internet users)
o 22.6 million US bloggers in 2007 (12%)
Universal McCann (March 2008)
o 184 million have started a blog worldwide, 26.4 million have started a blog in the US
o 346 million read blogs worldwide, 60.3 million read blogs in the US
o 77% of active Internet users read blogs
Other findings include this: "All blogs are not created equal." There are only 76,000 blogs with a Technorati Authority of 50 or higher.
The majority of bloggers that Technorati surveyed currently have advertising on their blogs. Among those with advertising, the mean annual investment in their blog is $1,800, but it's paying off. The mean annual revenue is $6,000 with $75K+ in revenue for those with 100,000 or more unique visitors per month.
Four in five bloggers post brand or product reviews, with 37% posting them frequently. And one-third of bloggers have been approached to be brand advocates.
There's lots more data -- and some eye-catching charts like the one above. Check out Technorati's State of the Blogosphere 2008 for yourself.
