Out-stream refers to a type of online video advertising that is displayed outside of traditional video content, such as within articles or social media feeds. Unlike pre-roll or mid-roll ads that interrupt the viewing experience, out-stream ads are seamlessly integrated into the user’s browsing experience, allowing for a more natural and non-disruptive form of advertising. These ads typically autoplay without sound and can be clicked on to expand and play with sound. Out-stream ads are becoming increasingly popular due to their ability to reach a wider audience and provide a more engaging and less intrusive form of advertising.
