Use of Ogg formats in HTML5
, HTML5 video is not currently as widespread as Flash videos, though of recent rollouts of experimental HTML5-based video players on websites, DailyMotion is so far the only one to use Ogg Theora and Vorbis formats, which suggests an increasing early interest in adopting HTML5 video.
Adobe Flash
Although Flash was previously a dominant platform for online multimedia content, it is slowly being abandoned as Adobe favors a transition to HTML5 due to inherent security flaws and significant resources required to maintain the platform. Apple restricted the use of Flash on iOS in 2010 due to concerns that it performed poorly on its mobile devices, had negative impact on battery life, and was deemed unnecessary for online content. As a result, it was not adopted by Apple for its smartphone and tablet devices, which also reduced its user base and encouraged wider adoption of HTML5 features such as the canvas and video elements, which can replace Flash without the need for plugins. In 2015, Adobe rebranded its Flash authoring environment as Adobe Animate to emphasize its expanded support for HTML5 authoring, and stated that it would "encourage content creators to build with new web standards" rather than using Flash. In July 2017, Adobe announced that it would declare Flash to be end-of-life at the end of 2020, and will cease support, distribution, and security updates to Flash Player. After the announcement, developers have started a petition to turn Flash into an open-source project, leading to controversy.
