NetChoice, an e-commerce trade group, has raised concerns about do-not-track efforts in Congress. Targeted advertising helps pay for free applications and content on the Web, and a government-enforced do-not-track mechanism could cause major damage to the online advertising industry, said Steve DelBianco, NetChoice's executive director.
But privacy and civil liberties groups said the do-not-track legislation is needed because there are few limits on the amount and type of personal information Web-based companies can collect.
The legislation would give "Americans the right -- and the right tools -- to browse the Internet without their every click being tracked for marketing or other purposes," said Susan Grant, director of consumer projection at the Consumer Federation of America. "Right now, the privacy interests of individuals who go online and the interests of advertisers and others who want their personal information are woefully out of balance."
Other groups expressing support for Rockefeller's legislation included the Electronic Frontier Foundation, Consumer Action, and the Center for Digital Democracy.
