The announcement was made with the publication of Netcraft’s November 2006 Web Server Survey.
“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 report said.
The survey went on to report that the explosive growth of blogs and server message block websites were the two chief influences in the surge.
Among the web servers in use, Apache took the top spot with a 60.3 percent market share. Microsoft was second with 31 percent, followed by Sun with 1.7 percent and Zeus with 0.5 percent.
The 100 million mark was passed a mere 15 years after the Internet’s first website, info.cern.ch, came online August 6, 1991.
