# Picture in Picture, a cool feature for the web
Picture-in-Picture made its first appearance on the web in the Safari browser with the release of macOS Sierra in 2016. It made it possible for a user to pop a video out into a small floating window that stays above all others, so that they can keep watching while doing other things. It’s an idea that came from TV.
There are 2 web API, relevant from it. MediaStream (opens new window) and Media Devices (opens new window)
Here is the code that i use from the course 20 Web Projects (opens new window)
Below i left the demo and repo url
