  Beginning with the enigmatic (and now emblematic) TW Hya, the scutiny of
individual stars and star-disk systems has both motivated and benefitted from
the identification of nearby young moving groups (NYMGs). I briefly outline the
emergence of this relatively new subfield of astronomy over the past two
decades, and offer a few examples illustrating how the study of NYMGs and their
members enables unique investigations of pre-main sequence stellar evolution,
evolved protoplanetary disks, and young exoplanets.
