There are now more than 100 million web sites on the Internet, which gained 3.5 million sites last month to continue the dynamic growth seen throughout 2006. In the November 2006 survey we received responses from 101,435,253 sites, up from 97.9 million sites last month.

The 100 million site milestone caps an extraordinary year in which the Internet has already added 27.4 million sites, easily topping the previous full-year growth record of 17 million from 2005. The Internet has doubled in size since May 2004, when the survey hit 50 million.

Blogs and small business web sites have driven the explosive growth this year, with huge increases at free blogging services at Google and Microsoft. Domain industry juggernauts Go Daddy (U.S.) and 1&1 Internet (Germany) have also seen strong demand for low-priced domain names and shared hosting accounts.

The first Netcraft survey in August 1995 found 18,957 hosts, with the NCSA web server dominating with 57 percent market share, leading CERN (19%) and a newcomer named Apache (3.5%). Microsoft's Internet Information Server launched in February 1996, and by the survey's fifth birthday the server market was largely divided up between Apache and IIS. This month Apache leads with 60.3% market share, with Microsoft at 31.0% and Sun at 1.7%.

Previous milestones in the survey were reached in April 1997 (1 million sites), February 2000 (10 million), September 2000 (20 million), July 2001 (30 million), April 2003 (40 million), May 2004 (50 million), March 2005 (60 million), August 2005 (70 million). April 2006 (80 million ) and August 2006 (90 million).
