Must See TV

"Must See TV" is an advertising slogan used by the National Broadcasting Company (NBC) to brand its prime time blocks of sitcoms during the 1990s, and most often applied to the network's Thursday night lineup, which featured such popular sitcoms as The Cosby Show, Family Ties, Cheers, Night Court, A Different World, Seinfeld, Mad About You, Wings, Frasier, Friends, NewsRadio, and Will & Grace (as well as such drama series as Hill Street Blues, L.A. Law, and ER) and allowed NBC to dominate prime time ratings on Thursday nights in the 1980s and 1990s. Ratings fell in the mid-to-late 2000s, and now is called "Comedy Night Done Right".
