Top 10 Most Popular Online Brands In April 2010 (PHOTOS)

What brands do you visit the most online? The answers may surprise you.

Nielsen has released a study of the world's internet usage in April 2010.

According to their research, users now spend a full 22% of their time online (or one in every four-and-a-half minutes) on social networking sites like Facebook, YouTube, and Wikipedia. Nielsen also reports that in April 2010, "for the first time ever, social network or blog sites are visited by three quarters of global consumers who go online, after the numbers of people visiting these sites increased by 24% over last year."

Nielsen also tracked the top ten most popular brands online for the month of April 2010, measured in terms of the percent of the world's internet population visiting the brand and the average person's time spent on that brand's sites. Though Facebook did not make the top spot, visitors spent an average of 6 hours on the site in the past year. This is far and away the longest amount of time that users spent with an online brand.

See what brands made the top 10--and how long people spent on that online property--in the slideshow below.
