Channel One - In my opinion, it's too commercialized and somewhat annoying, but it does get some of the news out to high school kids, and it's definitely real! It lasts about 12 minutes and is shown every morning in most high schools.
Side point - Channel One was the way many schools got a TV in every classroom. When the schools promised to show Channel One on a daily basis in the early or mid-90's, they got a TV for every room. Not a bad deal!
