"Since the advent of people meters and the emphasis on adults 18-49, the audience advertisers covet is just not readily available on Friday or Saturday," points out Jeff Bader, executive vice president, planning, scheduling and distribution, ABC Entertainment Group. "Economically, it's very difficult, if not impossible, to assemble an aggressive night of programming on both nights similar to earlier in the week simply because of the lack of target viewers and weaker advertiser support. The desirable audience is just not available."
