Throughout the 1960s and 1970s Sweden was seen as an international leader in what is now referred to as the "sexual revolution", with gender equality having particularly been promoted. The early Swedish film ''I Am Curious (Yellow)'' (1967) reflected a liberal view of sexuality, including scenes of love making that caught international attention, and introduced the concept of the "Swedish sin" that had been introduced earlier in the US with Ingmar Bergman's ''Summer with Monika.''
