Facebook started out in 2004 as an online hangout for college students. Now it looks like the baby boomers are crashing the party. Membership on the social-network site of U.S. users age 55-plus shot up 25%, to 7.3 million, in the one-month period ending Aug. 4, according to Washington researcher iStrategyLabs, which collects data Facebook gives to advertisers.

Older Facebook users now represent about 10% of the total 77.7 million registered with the site in the U.S., according to iStrategyLabs data.
