Even with the commercials, it is best not to let the whole thing get dragged out for too long, otherwise, it would be too long and would bore the viewers and lose them in terms of television ratings, possibly even damaging the show's reputation to some extent. It is good to make it longer than the specials (1 - 1 1/2 hours without the commercials), so that it is at a good length to be entertainment, but not long enough to be bore the viewers.
