During the Web 2.0 summit, Marissa Mayer told the audience to expect Google Health early in 2008. Marissa has taken over the project started by Adam Bosworth -- an ex-Googler (he recently joined Facebook) who has spent much time talking to people about how Google will play a part in the healthcare industry. Early screenshots of the service surfaced in August, and since then Microsoft has officially entered the space with their own solution.
It will be interesting to see how Google can leverage their "immense data storage and organization capacities" in the healthcare space.
Google has developed a prototype online platform for its health offering that incorporates personal medical records, health care-related search features, diet and exercise regimens, a localized "find a doctor" application, and other elements, Mayer confirmed. -- Information Week
