There was a seperate article about this a month or so back. I'm guessing the statistic are just skewed because new shows only air in a certain block of time like (something like 2 hours a day) N/7 days of the week. The vast majoirty of what is shown on the CW are reality shows outside of that block of time. If those out perform the given scripted original programming of the CW, then it very plausible the average age is that high.
