What would you call this type of news: Worst Passwords of 2014? I guess we could still call it news, but I'm curious if there's a special term for this because it's a little bit different from the format of news we're used to seeing on television.
Since that particular video is fairly serious and its title and content match, you might just call it a clip or simply a video without referring to its informative content.
John, check out this video about passwords. I bet I could get into your email with one of these!
Articles or videos that include a list of things are often just referred to as lists, again without referring to the style or intent of the content.
John, check out this list of passwords. ...
As I'm sure you've noticed, many of the articles and videos available on the internet are misleadingly or alarmingly titled, so if this were titled something like, "Don't Register for Another Account before Reading This!!!" then it might be called click bait (or clickbait.) That would imply that the advertising revenue of the video was more important than its content's quality or usefulness.
Me: John, I saw this video that basically says we're a bunch of idiots who always choose the same passwords.
John: Jason, why are you even watching that clickbait?
Finally, if the content of the video was the main focus, you might call that content trivia (or as Tetsujin suggests, factoids.)
