 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.
