Comparison of HTML5 and Flash
Until 2008, the use of Flash was covered by restrictive licenses. The conditions prohibited use of the specification to develop any software (including players) which could render or read (and thus convert) SWF files, and required the output SWF files to be compatible with Adobe's players.
