Flash
Flash was formerly called "Macromedia Flash", but is now relabeled as "Adobe Flash" since Adobe purchased Macromedia software in 2005.
Flash is streaming animation for web pages. Sometimes Flash is a portion of an html web page, and sometimes a web page is made entirely of Flash. Either way, Flash files are called "Flash movies". These are special .swf format files that beam to your web browser screen as you watch them.
