WebMD has acquired eMedicine.com, an online publisher of medical reference information for physicians and other health care professionals, for $25.5 million, WebMD said yesterday.“In combination with Medscape, eMedicine.com will strengthen our reach and expand the breadth and depth of our online clinical reference information,” said WebMD CEO Wayne Gattinella in a statement. WebMD said it expects to realize the full benefits of the acquisition after the integration of sales, technology and editorial infrastructure is completed in the latter part of 2006. For 2005, eMedicine.com’s estimated revenues were approximately $6 million.
