Adobe Flash Player is a software that must be installed on any machine that attempts to access Flash based content. Since Flash can be used for so many diverse things, not having Adobe Flash Player installed may prevent a user from accessing many different types of webpages and entire services.
For example, the popular video sharing tycoon, YouTube, runs entirely on Flash, allowing it to include clickable links directly within a video and display similar videos when a video is over. Essentially, Flash is used to provide interactivity within media content.

Advantages/Disadvantages
