The facts...?

I've been wondering the exact meaning of those interruption among 24CH△NNEL episode that putting the word CM.

Then read the translations (credit to Double 2 subs)

I remember that Riva who lived in Nara said that she never watch 24CH△NNEL because the show didn't broadcast in Nara.
So, no CM and that it doesn't widely broadcast are the reasons to stop the show? :(
Now, I wonder how the rating goes..
