Top 50 US web properties, September 2010

Online Gambling sites were popular in September as the competition heated up at several online poker tournaments. Classes resumed for schools and universities nationwide prompting teachers and students alike to visit Education sites.

"Education may begin in the classroom, but the Internet is becoming an increasingly important resource for students and an extension of the classroom environment," said Jeff Hackett, senior vice president of comScore Media Metrix. "The digital world enables the easy exchange of notes, lectures, examples, extra practice and other resources that help facilitate learning outside of the classroom."
