Some 50 million blogs, or online multi-media journals, were tracked on the Internet last month, a 100-fold increase over three years, a study, quoted by an AFP report said.
The AFP report said the study, published online by Technorati, a Web site devoted to tracking the growth of the worldwide 'blogosphere', claims that the number has doubled every 5 to 7 months since January 2004, and looks set to reach 100 million by next February.
Last month, Technorati said it logged 175,000 new journals every day, an average of two per second, with 1.6 million blog messages posted daily, double the volume of a year ago.
English-language sites make up 39% of the total, followed by Japanese at 31% and Chinese with 12%, the study said.
Some 8% of new blogs however are in fact spam sites, known colorfully as 'splogs," which have slipped through the search engine's net undetected, the study further said.
