CBS and other networks "within a year" will be using the C7 ratings metric, which will allow them to include DVR audiences for seven days after a show's original broadcast instead of the current three days, CBS chief Les Moonves said at an investor conference. Moonves also projected that CBS would once again lead the upfront and defended the network's demographic appeal. "The thing that the press writes that bothers me the most is that 18-to-49 is the only viewer the advertiser cares about," he said. "... The fact is, we win total viewers by more than we win every other demographic. We welcome everybody, and we sell to everybody."
