Blogs Burgeon To 50 Million, But Growth Is Slowing

The blogosphere has grown more than 100 times the size it was 2003, with Technorati tracking its 50 millionth blog, according to David Sifry's latest "State of the Blogosphere" report. However, Sifry, CEO of Technorati, said in his report that he thinks it's unlikely the number of blogs will continue to double every six months, as they have for about two years.

"As of July 2006, about 175,000 new weblogs were created each day, which means that on average, there are more than two blogs created each second of each day," he said in a statement posted on Technorati.

"Can this possibly continue," he asked. "Will I be posting about the 100 millionth blog tracked in February of 2007? I can't imagine that things will continue at this blistering pace - it has got to slow down."

Sifry said Technorati shows that the number of blogs doubled in 40 days at the end of 2003. In early 2004, the rate the blogosphere growth had slowed to the point where it doubled every four months. By July 2004, the blogosphere doubled in size every six months. That growth rate remained relatively stead until now, when it is taking closer to seven months for the number of blogs tracked by Technorati to double.

In July 2006, Technorati tracked 1.6 million postings daily, or 18.6 per second and postings increase with major news events. For example, this week, the most popular topics among bloggers include AOL, advertising, Bush, Flickr, Hezbollah, Iran, Iraq and Israel.
