Zucker became president of CNN Worldwide on January 1, 2013. His appointment was widely welcomed by the network and its anchors. Anderson Cooper told colleagues that Zucker was "the first CNN president to actually watch CNN". In December 2013, Zucker stated that his goal for the channel was to offer an "attitude and a take" to viewers, with a larger focus on reality-style documentary series (expanding upon the success of its documentary acquisition "Blackfish", and new series ""). Zucker explained that he wanted CNN to appeal more to regular viewers of factual networks (such as A&E, Discovery, and History), and make larger investments into the network's digital properties.
