Adobe's vice president of product development, Govind Balakrishnan, said the firm had chosen to end Flash because other technologies, such as HTML5, had "matured enough and are capable enough to provide viable alternatives to the Flash player".
Adobe said it does not expect Flash's sunset to have an impact on its bottom line.
2020 end - Adobe Flash is removed from Microsoft Edge and Internet Explorer. When Adobe acquired Flash in its 2005 purchase of Macromedia, the technology was on more than 98 percent of personal computers connected to the web, Macromedia said at the time.
Microsoft will then disable Flash by default in its two browsers in middle or late 2019, but people will be allowed to re-enable Flash in those browsers.
Those efforts will culminate with Adobe ending Flash support and distribution by the end of 2020.
The company suggests that developers switch from using Flash to modern web technologies such as HMTL5, WebGL or WebAssembly.
Apple did not want developers writing Flash apps instead of iPhone apps.
Flash led the way on the web for rich content, gaming, animations, and media of all kinds, and inspired numerous current web standards powering HTML5. We will remove Flash completely from Chrome toward the end of 2020.
"We remain fully committed to working with partners, including Apple, Facebook, Google, Microsoft and Mozilla to maintain the security and compatibility of Flash content", the Adobe announcement continues.
You'll soon be able to bid adieu to Flash. If the site migrates to open web standards, you shouldn't notice much difference except that you'll no longer see prompts to run Flash on that site. When retiring an application, it is important to manage expectations by establishing and communicating an end-of-life support policy that governs retirement and sets a clear end-of-support date-in this case no later than the end of 2020.
