NBC (CMCSA -0.2%) keeps its strong ratings rolling, beating network rivals for young viewers for three week running. While NBC has racked up a 15% increase in the 18-year to 49-year demographic this year compared to last, ABC (DIS -0.9%) is down 12% and CBS without Charlie Sheen to drum up business is down 24%. Analysts say one more week at the top could be enough to get ad rates heading north.
