YouTube recently released an update to the YouTube Creator Studio, Cards. Cards are somewhat similar to the existing Annotation feature in the Creator Studio which allows users to add text and clickable "hotspots" on their video that can direct a viewer to another YouTube video. Cards differ in their appearance and impact on the viewing experience. While Spotlight annotations would appear directly on top of the video, Cards appear as a small pop-up in the right hand corner of the video with a call to action created by the owner of the content. Also, at any point while viewing, all of the cards can be revealed, allowing the viewer to click at any point on any of the linked, associated content.
