The name of an online video commercial that appears at the end of an online video, it is typically :10 - :15 seconds in length. Once you click on certain online video links, you will be forced to watch a short commercial before the video content (known as a pre-roll) or after the video content (known as a post-roll).
Post-roll makes up a small percentage of the available interactive video inventory, but it is growing more popular because it is one of the simplest ways to utilize the Internet for sight, sound and motion.
