            You can add commercials for your event. These commercials will be displayed on the event detail site.
            If you don't add a commercial, the conference commercial will be displayed!
            We currently support the following commercial types: YouTube, Vimeo, Instagram, Flickr, Speakerdeck and SlideShare.
