What it was

A browser and desktop runtime for interactive multimedia created by Macromedia and later maintained by Adobe. Flash became a common delivery layer for animation, games, advertising, interfaces and early streaming video, supported by a huge creator-tool ecosystem.

Adobe and browser vendors give creators three years to migrate.
Adobe stops issuing normal security and product updates.
Flash Player refuses to run ordinary Flash content after the deadline.
Why it ended
Security risk, mobile incompatibility and the rise of open web standards led Adobe and browser vendors to coordinate retirement. Adobe stopped support at the end of 2020 and blocked playback in January 2021.
Last confirmed trace
SWF files, standalone projectors, emulators such as Ruffle and preservation projects retain large but incomplete portions of Flash culture.
What it left behind
Flash's afterlife is now a major digital-preservation effort because removing a runtime can erase millions of works at once.
