Flash animations are too slow and take too long to download. Flash animations are nothing more than eye candy, and ugly besides. No business serious about making money uses Flash on their site. You need to go through a long download process to get the Flash runtime files. Anyone can build a flash animation - it's easy.
Flash animations are too slow and take too long to download.
With all myth-conceptions, there is a grain of truth here, IF the flash developer is not careful and considerate about bandwidth and streaming issues. As a streaming technology, Flash can begin displaying an animation the moment it has downloaded enough relevant content. In other words, I can create a flash movie that begins to tell its story within a second or two of streaming download, if I carefully limit myself to some initial text and simple graphics. The rate of playback is usually slower than the rate of download, so as one set of actors appears on stage and does their thing, more 'actors' and 'scenes' can download in the background, patiently waiting their turn 'behind the scenes'. Certain Flash movies may require some heavier actors to appear from the first frame.
