Rejected by the courts in an earlier effort to restrict Internet pornography, the House voted Wednesday to require companies to verify an adult's age before showing online material "harmful to minors."

Included within the bill, passed on a voice vote, was a far less controversial proposal to require companies on the Internet to obtain parental consent before collecting personal information from children on the Web.

It would require companies online to make "any reasonable effort" to get parental consent before asking children under 13 for their names or e-mail addresses. The bill is significant because it would mark the first federal privacy protection for Internet users, but it specifically would not affect information collected from adults.
