### What is VAST?

The IAB Digital Video Ad Serving Template (VAST) specification is a universal XML schema for serving ads to digital video players, and describes expected video player behavior when executing VAST-formatted ad responses.

In short, VAST makes it possible for an ad provider to serve ads to various video players using a universal way of communication which all these players understand.

A thorough description of the overall idea behind VAST, as well as the full VAST specification, can be found here: [VAST 4.0](https://www.iab.com/wp-content/uploads/2016/04/VAST4.0_Updated_April_2016.pdf)
