Consumer health Web site drkoop.com has agreed to provide exclusive health-related content to EarthLink, the subscriber-driven Internet service provider. Health information will be available through the health channel link located on the EarthLink personal start page, the default home page for subscribers. The newly expanded health channel will feature thousands of drkoop.com health articles, health videos, interactive tools, a comprehensive encyclopedia and interactive medical animations. Content is organized by topic driven channels and offers a drug interactions tool for investigating potential adverse drug reactions for common prescription drugs. "Customers can use our health channel as their one-stop resource for health-related content, including one of the most comprehensive medical video libraries available online today," said Tom Andrus, vice president of products and services at EarthLink. Drkoop.com was recently acquired by Choice Media, a Somerville, N.J.-based firm specializing in online marketing and advertising sales. Other health-related Web sites either owned or exclusively represented by Choice Media include DrDrew.com, Healthscout.com, MDchoice.com and HealthCentral.com.
