Macromedia has just published the results of a September 2002 study on Flash penetration. That study was conducted by NPD Research, the parent company of MediaMetrix.
According to the study, nearly 98% of web users can see Flash content without having to download and install a player. More importantly, Flash 6 penetration was nearly 60% when this study was done. At the time, Flash Player 6 had only been out for about six months. 0-to-60 in six months. Wow.
This means that the installed base of video-/audio-capable Flash players is greater than Windows Media, greater than RealSystem, and greater than QuickTime. Wow.
Now if they could only get the video and audio to sync.
