YouTube and Vimeo is kicking Adobe's Flash to the curb in favor of the sharp new HTML5. Both YouTube and Vimeo have announced that they are launching HTML5-based players on their video streaming sites, thus booting out the long-standing champ of multimedia delivery, Adobe Flash. With recent security issues plaguing Adobe products, it's no surprise that media giants such as YouTube are jumping ship. What makes HTML5 special is that the new Web standard doesn't require Adobe's software to stream content to viewers.
