These jokers are journalists?
I'm not a Touhou fan or anything like that, but if I were in their shoes and wanted to report on this I'd at least do a little research on the video before reporting on it.
That being said usually news broadcasts only have so much time since they have to make room for advertisements; advertisements being how these news organizations earn their money. This is generally why you see stories like this only talked about briefly before they move on to something else. That being said they could have just as easily mentioned that the animation was based off of characters from the Touhou series.
Honestly, this is why I feel more informed by the likes of the Colbert Report and the Daily Show.
