The role of the Drell-Yan process in studying nucleon spin is discussed. Recent results from the Fermilab E866 experiment on the angular distributions of Drell-Yan dimuons in p+p and p+d at 800 GeV/c are presented. These data are compared with the pion-induced Drell-Yan data, and with models which attribute the cos 2{phi} azimuthal distribution to the presence of the transverse-momentum-dependent Boer-Mulders structure function h{sub 1}{sup perpendicular}. Constraints on the magnitude of the sea-quark h{sub 1}{sup perpendicular} structure functions are obtained. Future prospects for studying the TMDs with Drell-Yan experiments at Fermilab and J-PARC are also discussed.
