Oh crap. Until I read this all through, I thought I was still on botbot. So I seriously took this as a real horrifying story, not as creepypasta. Needless to say, I'm probably not going to sleep tonight. Especially not with my habit of leaving the TV on.
You were doing so well until the bit about not being able to change the channel.
They are people out there stupid enough to not just change the channel, so when he mentioned the rogue channel I immediately thought "creepypasta", but a good one none the less.
I doubt that the real recording is still out there somewhere. He has a point with the audio being cut off, but it could also be sloppy editing. Being unable to change the channel sounds a bit farfetched as well.
I can't really take these kind of creepypastas seriously when they treat absolutely mundane things like eldritch horrors and put them in scenarios that would otherwise be easily avoided, i.e. the guys at CN only making the bump long enough for the few seconds it was supposed to last, not using a sound set that would horrify their viewers enough to negatively impact business, or viewers calling in CN begging them to make the sounds stop as opposed to, say, turning down the volume or changing the channel.
