In March 2013, as the nation’s highest court heard two landmark arguments on the legality of same-sex marriage in the U.S., the outpouring of support from Americans made it clear that gay marriage has already won. Polls show that more than 4 in 5 voters believe gay marriage will be legal within the decade, and public support — from politicians, celebrities and citizens alike — has never been higher, according to TIME’s cover story. Though the Supreme Court has not yet rendered a decision, and only nine states have legalized gay marriage, it’s clear that American society has reached a watershed moment.
