More than $100 million invested in building virtual health sites

Ninety-five million Americans -- about 80 percent of online adults -- have searched the Web for health information in the past year, and the overwhelming majority have been disappointed.

More than 70 percent of those searchers either did not find what they were looking for or had a hard time knowing what to believe, according to market research studies by Jupiter Research and Yankelovich Inc.

That frustration has attracted some famous deep pockets, including America Online co-founder Steve Case, his former employer Time Warner Inc., the Carlyle Group and Allen & Co. Together, they have put more than $100 million into building virtual destinations that offer consumers something beyond disease encyclopedias.
