Google, Facebook and Youtube have emerged as the most popular websites surfed by mobile handset users in 2011, according to a study.
The State of the Mobile Web report for 2011 by web browser company Opera Software took a survey of the most popular websites people surf from mobile web browser, Opera Mini.
According to the report, 2011 was the year of user-created content for Opera Mini users. Websites like Wikipedia and Blogger saw an increase in their number of unique visitors and crept even higher on the charts.
India is among the top two countries with a user base of over 1 million using Opera Mini for accessing the web from their handsets. Firmly at the top of the lists are the search, social network and video sites Google, Facebook and YouTube.
With more than 144 million people using Opera Mini each month worldwide, the top-ten lists are somewhat static.
Even so, a small change in list rankings can signify a huge shift in usage patterns, said the report.
Websites such as Google's social networking site Orkut, Live.com and Detik have dropped from the global top 20 sites.
