Why are different ads appearing in the News section of my website?

In the UK, many websites are able to include content from  Sky News, which is supplied thanks to a contractual agreement with IRN.

As part of the contract between the radio station and IRN, the webpages which display these stories must carry  IRN's national advertising.

The  roadblock feature of our Advertising app is used to ensure these ads only appear on the specific section of the website where they are required, and that no other ads appear there.
