Everyone makes mistakes. Even Google. If you missed it then check this link.
It seems ads for major UK brands have appeared as the ‘intro’ to some youtube videos posted by people with views that many would consider extreme or unsavoury. Google owns youtube of course and those ads that you can skip are a major source of income. The idea is that the ad is targeted in some way based on data about you or the people who access the video. Trouble is that this is all governed by machines (well machine learning and algorithms) and they can make mistakes. Marketing and marketing communications (like advertising) are increasingly automated. There is human oversight but it’s only oversight. Like any automated process it can go wrong and it did. The following video promoting Google Analytics through satire can now be viewed with some irony.
