One blog created 'every second'
In its latest State of the Blogosphere report, it said the number of blogs it was tracking now stood at more than 14.2m blogs, up from 7.8m in March.
It suggests, on average, the number of blogs is doubling every five months.
Blogs, the homepages of the 21st Century, are free and easy to set up and use. They are popular with people who want to share thoughts online.
They allow for the instant publication of ideas and for interactive conversations, through comments, with friends or strangers.
