Hey NOT...
I also suffered Channel One during junior high and high school ('90-'96). The anchors then were Anderson Cooper and good ole Lisa Ling.
What I remember most about it the VOLUME they played it at, and the "World-In-A-Minute" segment--in sixty seconds they recapped all the world news, barraging you with third-world images and lightning fast narration.
At the time I escaped it by drawing. I drew mazes and role-playing "board games" that I played with my friends during lunch time.
Your post reminded me of an assembly the school held once, too. It was eighth grade. Everyone was pulled out of class for a half a day for a "Pepsi Assembly." We watched an audio-visual presentation about the Pepsi company and their new product, "Pepsi Clear" (which bombed, by the way).
Music video pop songs (that everybody loved then) were incorporated into the presentation, with the Pepsi logo popping up again and again. Usually, our principal went to great lengths to keep us under control and quiet, but we were told that day that we could cheer and yell all we wanted.
Afterwards, the entire school was led into the cafeteria and we were given a free can of Pepsi Clear by Pepsi marketing reps and invited to offer feedback. I think we were even allowed to drink it in class that day... The next day there was a Pepsi Clear soda machine in the cafeteria and kids were talking about how cool Pepsi Clear was for a week...because it tasted like Pepsi...but it was clear.
To this day I associate the Ugly Kid Joe song "I Hate Everything About You" with Pepsi Clear and that memory. They played it in the assembly.
(Does anybody remember the kid who was suspended from school for wearing a Pepsi T-shirt on the day his school was shooting a TV commercial for Coca Cola?)
...Anyway...I had an idea, NOT. Maybe the Channel One time would be an opportune time to practice clearing your mind techniques. I'd just look at a spot right below the TV or something and watch my breathing, or single-pointedly focus on a feeling of joy inside me--let it build and build.
Your knowledge is already protecting you. The fact that you know that it's bullcrap is a big deal and half the battle.
As I thought about it, I also rememberd www.psipog.net. On that site they have info on creating "constructs," which could be used as mental-energetic barriers between you and your teachers, less-evolved classmates and the loud TV. A construct is a thought-form that you program to do anything you want.
I sometimes place protection constructs between me and a particularly scary movie, and let the construct absorb the fear energy. 
Don DeGracia said that the best way to overcome your fear is to study it. I was afraid of propaganda so a couple of years back I read "Mein Kampf" by Adolf Hilter. His book has a chapter on propaganda and how he used it. (BTW, he notes that most of his propaganda know-how came from watching the Americans in WW1). He defines three main components of propaganda: slogans, emotionalism, and simplicity.
If I'm ever unsure if I'm being propagandized to, I look for those elements. The media blitz after 9-11 obviously contained all of them: The Slogan="United We Stand," or "God Bless America" (take your pick); The Emotionalism=Video footage of beaten, but not beat hero fire-fighters; The Simplicity=War is the answer.
You can't change a tiger's stripes,
but you can avoid its teeth.
