Panel show panel shows marked a shift in the format: Whereas CBS' primetime shows had panelists guessing secrets about the guests, these new shows largely had panelists playing games with guests. Later, the U.S. version of "Whose Line Is It Anyway?" had a primetime run from 1998 to 2004 on ABC, while "Wait Wait... Don't Tell Me!" has become a popular weekend show on NPR since 1998. While "Wait Wait" continues to find success on the radio with a format driven by comedic banter similar to British shows, U.S. TV panel shows currently employ a format closer to traditional game shows that
