Facebook is booming with Boomers

Some might call it the graying of Facebook, others its maturation. By any measure, it reflects the growing popularity of the world's biggest social-networking site.

Last year, social media boomed for Baby Boomers: 47% of them actively maintained a profile, compared with 32% in 2008, according to eMarketer.

Boomers inexorably drifted to Facebook. Nearly three-quarters had a Facebook account. Only 13% used Twitter.

Make no mistake, however:  the digitally connected tend to skew young. They are imbued with social media, as exemplified by use among millennials (77%) and Generation Xers (61%).
