The Downside of YouTube

I was looking up videos today to explain an important battle that the Romans fought against the Gauls and had trouble finding something appropriate.  There are videos that are appropriate but I can't use them.  The problem is the suggested videos that come up on the side of the YouTube video if you go to that instead of using the embedded version on the site.  I was surprised to find what looked like inappropriate sexual content.  I can almost imagine the discussions I would be having with my supervisor if I had not caught it.  Unfortunately this is one of those areas that is hard deal with.  I want to have the kids be able to look up and see all the great stuff out there but worry about the muck that will get through.  I looked up videos on TeacherTube but there were a lot fewer options. I will have to work to figure out what the balance is on this.
