Prebid Video | Instream Example with JW Player (Self-Hosted)

An example of an instream pre-roll ad using Prebid.js and JW Player (Hosted).

Important: This example uses a test version of Prebid.js hosted on our CDN that is not recommended for production use. It includes all available adapters. Production implementations should build from source or customize the build using the Download page to make sure only the necessary bidder adapters are included.

Warning: Do not forget to exchange the placementId in the code examples with your own placementId!
