Flash has been around for over a decade and has been used to create everything from animated websites, to applications, to audio and video streaming platforms (like YouTube). In the last 5 years, there has been a web design movement away from using Flash, especially when used to create an entire site. Apple's stance on Flash and not including compatibility with its mobile hardware (iPhone, iPod, and iPad) has furthered this movement. In its place, CSS3 and HTML5 are being used.
