It appears that a major source of video revenue for storm chasers is in jeopardy. This week, facing pressure from major advertisers, Youtube began dropping monetization from scores of videos citing a new, more stringent advertiser-friendly policy regarding content that receives Adsense revenue. The new policy targets videos that cover controversial or "sensitive" subjects like political discussion, war and natural disasters. The pressure comes after a barrage of mainstream media stories about ads that were found to be playing on videos that contain controversial material. A few major corporations pulled their ad campaigns from the site in response, motivating Youtube to make the policy changes. I was not aware of this until recently, when one of my popular winter driving videos was de-monetized. Many popular channels have been hit, including some with millions of subscribers. I also received word from a longtime experienced chaser that all of their tornado videos were de-monetized. Of concern is the following bullet item in the new policy: Link to the full text of the policy: https://support.google.com/youtube/answer/6162278?hl=en Blog post from Google on the subject: https://productforums.google.com/forum/#!topic/youtube/09dw40n0iwY The criteria are sweeping, covering anything that could be deemed "controversial", including political commentary. The notification I received was apparently an automated bot that I could appeal, which I did. This could be a significant development in the chasing media world, should this play out across all channels that have weather videos covering tornadoes, floods, winter storms, hurricanes and more.
