Ajax
Coined by James Garret:
"Ajax, for Asynchronous JavaScript + XML. Weaving together existing technologies, Ajax will help make Web services feel more like programs that run on the user's own computer, Garrett says, releasing Internet content from the limitations of conventional Web design by reimagining the browser as an operating system."
