Youtomb is a MIT Free Culture research project that monitors the most popular Youtube videos for copyright related takedowns. The project is currently monitoring more than 220000 videos on Youtube and noticed that almost 8% of the monitored videos have been taken down.
The website lists a screenshot and the name of the video, the category that it appeared in at Youtube and the views that it received. The most interesting information provided is probably the name of the company or individual that asked for the takedown of the video. Lastly the date of the takedown and the time the video was available at Youtube is also mentioned.
The statistics page lists all the reasons why a video was taken down. Exactly 4413 videos have been taken down due to alleged copyright violations while the remaining 13424 videos have been taken down for other reasons including adult content and TOS violations.
You can sort videos that have been taken down by company, which in turn highlights some of the companies that are most active on YouTube in regards to the taking down of videos on the site.
The monitoring appears to be still active these days. What's missing however is an update of the database of monitored videos on YouTube. When you look closely, you will notice that the latest take down notices the service recognized date back three years. It seems that neither the monitored videos nor the take downs have been updated since that time, which is a strong indicator that the project has been abandoned by the researchers.
The stats seem to be broken as well. The service claims to monitor 440k videos, of which 9760 have been taken down for copyright violations and 212k for other reasons.
