My question is: Why don't they? Why maintain such mind-numbing repetition?
There are dozens of threads on this board that all ask the same exact question. It's been answered with MIND NUMBING REPETITION and you simply don't like the answer.
The older you get, the more this kind of thing will bother you. Trust me, we've done studies. Babies love mind-numbing repetition. Their favorite word (other than no) is "Again." What's a problem for you clearly isn't a problem for a majority of their listeners, most of whom are probably younger than you. If it was, we'd see different results in the ratings.
So do us all a favor and please MOVE ON.
