Old and young use Internet differently (in US)

US survey - includes link to a PDF file of the 5 page report.

Excerpt:
"Compared with teens and Gen Y, older generations use the internet less for socializing and entertainment and more as a tool for information searches, emailing, and buying products. In particular, older internet users are significantly more likely than younger ones to look online for health information. Health questions drive internet users age 73 and older to the internet just as frequently as they drive Gen Y users, outpacing teens by a significant margin. Researching health information is the third most popular online activity with the most senior age group, after email and online search.

"Internet users ages 33-72 are also significantly more likely than younger users to look online for religious information and are more likely to visit government websites to search for information."
