Non-skippable ads are video ads that appear before, during, or after YouTube videos and playlists. When a non-skippable ad displays before a video, the viewer is forced to watch the full ad before the desired video starts playing. Simply adding a - after the t in youtube in any YouTube video (watch page) URL solves that issue by instantly linking to the ad-free, looped, full screen version of the video. Now, without having to download or install ad-blocking software, users can watch YouTube videos and playlists on repeat, free from all those annoying advertisements.
