This situation in the UK doesn’t seem to be getting much attention here in the US, but it should be, because although the boycott is UK-only for now, the issues at stake aren’t UK-specific at all and could easily spread to other markets. What’s happened is that some UK companies as well as the UK government have become increasingly concerned that their ads on YouTube have been appearing next to some pretty undesirable videos featuring extremism or promoting terrorism, and Google’s tools for avoiding this don’t seem to be doing their jobs. As a result, several companies and the government have now stopped advertising on Google at all as a protest until Google fixes things. A blog post from Google makes clear just how hard it is to police the video on YouTube – 400 hours of video are uploaded every hour, and it stopped ads from showing on 300 million videos last year, which provides some sense of the scale and the impossibility of monitoring all this with human beings alone. Google is never going to be able to police the content itself at sufficient scale and with sufficient accuracy to solve the problem directly. The solution is therefore probably paring back the kinds of videos on which at least certain ads would appear – such as limiting big brand advertising to channels with long histories, large numbers of subscribers, and a good track record. However, it’s likely that many brands would choose to limit themselves to this higher quality material, which in turn would mean the long tail of videos on YouTube might go un-monetized or monetized at a much lower rate, which would have a severe impact on not just creators but YouTube’s financials. Not only could this problem spread to other markets, but Facebook will have to deal with many of the same issues as it ramps up video advertising on its platform.
