At present, FLV is the file format widely used by some famous websites, such as YouTube, Google Video, MySpace, etc.

More specifically, SWF is a proprietary file format for multimedia and especially for vector graphics. It can contain animations or applets of varying degrees of interactivity and function in order to be small enough for publication on the Web. Therefore, SWF is currently the dominant format for displaying animated vector graphics on the web which is very popular and be commonly used.
