However, video and audio are only a small subset of sites that require flash. Granted, in terms of "number of Flash files downloaded" or "number of sites serving Flash content", the percent of video/audio-only Flash files may be small. But in terms of "number of Flash files downloaded that people actually came to the site to see" or "number of Flash files people would watch even if they were running Flashblock", I'd guess that audio/video-only files account for almost all of them.
