Love when reports use "median" anything...largely a useless statistic. The median age has little to no relationship to the average age of viewers.
Knowing that the youngest person in the oldest half of the TV population is getting older does tell you something interesting, and slightly more specific than what the mean gives you, although I suspect mean and median are fairly close in this case.
Of course it would be nice to have mean, standard deviation, median, and maybe a few other percentiles. Better, a full histogram. But median is hardly useless.
