New research from Pew/Internet shows that online people are increasingly using video-sharing sites like YouTube as part of their “typical day,” with online women making the biggest gains.

According to a “Pew Internet Project Data Memo” released today, nearly half of all Internet users (48 percent) have ever visited a video-sharing site, while the number of Internet users who visit video-sharing sites on a typical day nearly doubled, to 15 percent in 2007 from 8 percent in 2006. The number of online men rose to 20 percent from 11 percent year-over-year, while the number of online women using video-sharing sites more than doubled, to 11 percent in 2007 from 5 percent in 2006.

This 9 percent gap between male and female Internet users falls in line with previous Pew research showing that 19 percent of online teen boys posted video online to share while only 10 percent of online teen girls did so.
