"Adobe® Atmosphere™ is an interactive 3D multimedia creation and delivery platform for the Web and PDF. Atmosphere allows you to assemble graphics, video, audio, and 3D objects into rich, immersive, engaging experiences that go far beyond flat, static pages. Designers and developers use Atmosphere to inform, instruct, entertain, and sometimes just have fun."
"Adobe Atmosphere (abbreviated Atmo) is a 3D computer graphics creation product originally developed by Attitude Software. In November 1999, Adobe Systems purchased the technology. Adobe released its last version of Atmosphere, version 1.0 build 216, in February 2004, then discontinued the software in December 2004. The product spent the majority of its lifetime in beta testing."
