A few years ago it was unfathomable to see anybody over 50 on websites like Friendster and MySpace, but that's becoming a more common sight.
More young people are seeing their parents and grandparents on social networking websites such as Twitter and Facebook, reports CNN.
In fact, the rate of people over 50 interacting on social media websites is growing at a startling pace. A survey by the Pew Research Center found that social networking among internet users 50 and older nearly doubled, from 22 percent in April 2009 to 42 percent in May 2010.
For those ages 65 and older, use of social networking websites grew 100 percent. By comparison, the number of internet users from 18 to 29 who use social networking websites only rose by a dismal 13 percent.
"E-mail is still the primary way that older users maintain contact with friends, families and colleagues, but many older users now rely on social-network platforms to help manage their daily communications," explains Mary Madden, Senior Research Specialist and author of the report.
So internet users should be careful about what they post on Facebook or Twitter. Grandma might be watching.
