The multiscreen video platforms are the oft-forgotten heroes of video advertising, especially when it comes to delivering TV-quality linear streams. Before an ad is served, the content has to be marked for ad insertion and data is often passed between the content streaming platform and the ad server to ensure the right ad hits the right user. And then of course features like content personalisation boost inventory by making the content ‘stickier’.
