from cable channels aimed at the demographic; the network instead turned over two of the four vacant Saturday morning hours to its affiliates to allow them to air local newscasts or educational programs purchased from the syndication market, while it retained the remaining two hours to run a network-managed paid programming block, Weekend Marketplace, which debuted on January 3, 2009.

However, it does produce some content that is carried by the broadcast network, which is usually separate from the news coverage aired by the cable channel; in particular, FNC anchor Bill Hemmer anchors most prime time news presentations on the Fox network, especially during political
