Adobe Flash Player was the browser plug-in that brought rich animations and interactivity to the early websites.

Originally released in 1996, “Flash” was one of the most popular ways for people to stream videos and play games online but it was plagued with security problems and failed the tranistion into smartphones which ultimately has led to its demise.

Adobe (who made Flash) will no longer offer security updates for Flash and has urged people to uninstall it. It will also stop videos and animations running in its Flash Player from 12 January.

In 2009 Adobe said Flash was installed on 99% of internet-connected desktop PCs and Laptops and was used on 70% of all websites in some form.
