RevolutionHealth.com, the new health portal created by former AOL co-founder Steve Case, launched Monday, offering both free and subscription services that include the ability to store medical records online and get over-the-phone help in dealing with insurance companies. An annual subscription of under $100 would also let members pose questions to health experts by phone and download medical expense management software. The free, ad-supported version includes "health centers" covering a variety of topics, consumer ratings of doctors and hospitals, and a social networking component. Advertising on the site so far appears to be mostly house ads. To keep pace with growing competition from RevolutionHealth and other new health sites, category leader WebMD is revamping its site with new tools and expanded health information. Other new or upgraded health portals vying for pharmaceutical industry ad dollars include iVillage Total Health, Waterfront Media's EverydayHealth.com and TheHealthCentralNetwork.com.
