Anyone else find ads in the middle of videos on Facebook annoying?

So there I am watching a video on Facebook of an Irish priest singing R.E.M.'s song "Everybody Hurts" on Britain's Got Talent, which I am very much enjoying, when all of a sudden the video gets interrupted by an ad. Before, there were no ads in Facebook videos. Now they exist in every video I watch and I find that very annoying, especially if I am watching a video of someone sing. If having ads in videos on Facebook is a necessity why can't they run the ad before the video starts? Or perhaps have the ad at the end of the video? Though if the ad is at the end chances are people will move on and will not watch it. Anyone else find ads in the middle of videos on Facebook annoying or am I the only one?
