# Online video (OLV)

Online video (OLV) is a dynamic media channel that brings your message to life through a wide range of paid video ad formats delivered to digital devices. Whether it’s pre-roll, mid-roll, or post-roll ads during streaming content, out-stream video within articles or social feeds, or engaging interstitials on mobile apps, online video offers flexible and compelling ways to connect with your audience.

**Available formats:**

* **Instream:** Video ads that play before, during, or after online video content, capturing viewers’ attention where they’re already watching. *Example: A 30-second video ad shown before a YouTube video.*
* **Outstream:** Video ads displayed outside of traditional video content, typically embedded within articles or social media feeds as users scroll. *Example: A video ad that begins playing automatically when it comes into view on a news website.*
* **Interactive:** Ads that invite viewers to engage—by clicking, swiping, or making choices within the video for a more personalized experience. *Example: A car video ad where viewers can click to explore different models or features.*
* **Rich media:** Interactive formats that combine video with other dynamic elements such as animations or audio, often encouraging direct user interaction. *Example: A pop-up video ad that plays when you hover over an image on a webpage.*
* **Native:** Video ads designed to blend seamlessly with surrounding content, offering a viewing experience that feels natural and unobtrusive. *Example: A sponsored video on Facebook that looks and feels like regular user-generated content.*

**Targeting strategies supported:** Contextual, retail, behavioral, demographic, and geographic
