YouTube and other video-sharing sites are fast becoming a part of our daily life. So says a survey released this week by the Pew Internet and American Life Project. For example, the number of wired adults who visit a video-sharing site on a typical day has almost doubled in a year. The survey, conducted in December 2007, included 2,054 Americans age 18 and older. In 2006, 8 percent of Internet users had visited a video-sharing site the day before the survey; that number jumped to 15 percent in 2007.\n\nThat growth is largely driven by wired adults under 50. Thirty percent of adults between 18 and 29 who have Internet access visit a video-sharing site on a typical day, up from 15 percent last year.\n\nThe report says this growth links to the much bigger story: All types of websites\u2014not just Web 2.0 sites\u2014are quickly ramping up their video offerings.
