Deadline: Discovery CEO David Zaslav seemed more skeptical than usual about the growth prospects for U.S. television in his appearance before investors at the Bernstein Annual Strategic Decisions Conference. He provided a dreary report about everything from domestic advertising to content sales as he talked up Discovery’s international growth efforts. Zaslav described the current upfront ad sales market as “pretty good, but not great” as the number of orders ebbs. “We’re not fully monetizing our ratings points,” he says. “The volume is not what we’d like it to be” — although it’s “significantly better” than it was.
