186 million websites according to Netcraft
According to Netcraft, Internet counts about 186 million websites. That corresponds to a growth of over 30 million in comparison to 2007. In terms of percentages, this growth is not that spectacular: only 17%. As a matter of fact, the year before, this growth reached 40%. In 1995, there were less than 20,000 websites.
However, Netcraft underlines that, in its calculations, it took into account all registered domain names (of which less than half are actual active sites), and that lots of them are only meant to redirect visitors to obscure websites.
