Except that this is not an upwards trend. In 25-54, KLOS was at a 3.1 in June, then a 3.1, 3.2, 3.8, 3.4, 2.9 and 2.8 through December.
It is as if they had good growth the middle of the year, and by November were declining back to the level they were at last January and February, a 2.8. Even in the deceptive 12+ numbers, they are well below the mid-2019 numbers.
