The story
Blausen Medical Communications is a privately held company founded by Bruce Blausen in Houston, Texas in 1991. BMC created and owns a library of medical and scientific images and animations, and has developed information technology tools allowing access to the library; as well, it licenses and otherwise works to distribute the content.
As of this date, BMC's animation library comprised approximately 1,500 animations and over 27,000 two- and three-dimensional images designed for point-of-care patient education, which could be accessed by consumers or professional caregivers (primarily via hospital or healthcare portal websites). The company first packaged a number of animations and still images integrated within a functional dashboard player, sold as the Blausen Human Atlas.
In 2014, BMC released 266 of their images under a creative commons license, allowing for their free use.
The company has released the Blausen It web extension as an app to allows users to access Blausen 3D animations without visiting the company's website; clicking on the free app's icon in a web browser initiates a scan of the online text being viewed, resulting in highlight terms with icons that link to the company's educational animations.
