In popular culture, the phrase is most strongly associated with the network's entire Thursday night lineup, including both sitcoms and dramas, which dominated the ratings from the 1980s through the late 1990s.
However, contrary to popular belief , "Must See TV" originally applied to sitcoms only (dramas would normally be promoted separately), and for much of the 1990s the phrase was used several nights a week as an attempt at brand extension.
