I always like revisiting these stats each year as it indicates trends.
To bring you these answers, weve gone to the ends of the web wherever that is and back again, and compiled a list of truly fascinating facts about the year that was. Some of the numbers are snapshots taken during the year, others cover the entire period. Either way, they all contribute to giving us a better understanding of Internet in 2012.

Here are some stat snippets from the survey.
2.2 billion Number of email users worldwide.
144 billion Total email traffic per day worldwide.
61% Share of emails that were considered non-essential.
4.3 billion Number of email clients worldwide in 2012.
35.6% Usage share of the most popular email client, which was Mail for iOS.
425 million Number of active Gmail users globally, making it the leading email provider worldwide.
68.8% Percentage of all email traffic that was spam.
50.76% Percentage of all spam that was about pharmaceuticals, the top category of all spam.
0.22% Share of worldwide emails that comprised some form of phishing attack.
-6.7% Decline in the number of Apache websites in 2012.

36.4% Growth in the number of NGINX websites in 2012.
15.9% Growth in the number of Google websites in 2012.
it would be impossible to know what backend servers (that are doing all the real work) are actually running. for example, i have recent experience with a site using nginx as a load balancer while the site is actually served from apache servers. if they had moved from a straight apache environment to the load balancer configuration in 2012 that would have shown up in this survey as a decline in apache and a growth in nginx, yet the nginx server is doing practically nothing.
