The phenomenon of date rape is relatively new. Historically, date rape has been considered less serious than rape by a stranger. Since the 1980s, it has constituted the majority of rapes in some countries. It has been increasingly seen as a problem involving society's attitude towards women and as a form of violence against women. It is controversial, however, with some people believing the problem is overstated and that many date rape victims are actually willing, consenting participants, and others believing that date rape is seriously underreported and almost all women who claim date rape were actually raped.
