They now want Congress to curtail the practice of tracking consumers online to tailor ads more effectively.
Yahoo, Microsoft and Google all use targeted online advertisements.
"It’s not just about the right ad at the right time, it’s about
creating a profile about you," said the Centre for Digital Democracy’s
"These companies want to know about your likes and dislikes, if you
are Hispanic, do you vote, are you on a low income or a high income,

"It’s about a system that not only targets and influences the
products you buy but is also a powerful and invisible system of digital
persuasion designed to change attitudes and awareness," Mr Chester told

It will also seek to ensure no data is collected around financial or health matters. The key, many say, is transparency.
"An individual’s data belongs to them and before these companies

in July to address concerns around the issue.
"The vast majority of what happens online is truly anonymous and all
marketers and publishers are trying to do is deliver an ad that has
some relevancy to the person viewing it at a certain time," Mike
Zaneis, vice president of public policy for the Interactive Advertising Bureau told BBC News.
"The beautiful thing is they don’t have to click on that advert, or pay attention to it or do anything."
While Mr Zaneis agreed more has to be done to educate consumers
about the issue, he also warned that pushing for a blanket "opt in"
measure would be disastrous.
"A broad ‘opt in’ would be a sea change and it would be a recipe for disaster. It would kill the goose laying the golden egg. The goose is the internet and the golden egg is the free content
and services that consumers enjoy and that would be diminished," said

Consumers Union, Electronic Frontier Foundation, Privacy Lives, Privacy
Rights Clearinghouse, U.S. Public Interest Research Group, World
Privacy Forum, Privacy Times and the Consumer Federation of America.
