Must See TV: Must See TV was an advertising slogan that was used by the National Broadcasting Company (NBC) to brand its prime time blocks during the 1990s, and most often applied to the network's Thursday night lineup, which featured some of its most popular sitcoms and drama series of the period, allowing the network to dominate prime time ratings on Thursday nights in the 1980s and 1990s.  Ratings for NBC's lineup fell during the mid-to-late 2000s, and today the network ranks behind Fox, ABC and CBS on Thursday nights.  In 2015, the network canceled comedy programming on Thursdays and switched entirely to dramas.  However, the branding is set to return for the 2017-18 TV season.
