That's less than 20 million (19,940,000) for all three combined, and a 5.4% drop from the low-water mark of a year ago. The 25-54 demo for all three nets was under 6 million (5,920,000), and their combined 25-54 demo ratings of 4.9/21 are down 14% and 19% from last year's 5.7/26. Ouch.You don't suppose that almost 20 years of Media Research Center truth-telling about the relentless bias in the nets' evening news shows might have something to do with the ongoing decline? Nah, can't be (/sarcasm).
