Adobe Flash was a multimedia software platform used for creating animations, web applications, and games. It allowed developers to design interactive content that could run on various devices and browsers. Flash was widely popular in the early 2000s for its ability to deliver rich graphics and audio over the internet. However, as technology evolved, Adobe Flash faced challenges due to security vulnerabilities and the rise of more modern web standards like HTML5. In 2020, Adobe officially ended support for Flash, encouraging developers to transition to these newer technologies for creating interactive web content.
