Sean Sasser, who became an unlikely pioneer of gay marriage during the 1994 telecast of MTV's "Real World: San Francisco," has died.
Sasser, who was 44, suffered from a rare form of lung cancer, according to UPI.
"We will miss u so much," Judd Winick, one of Sasser's "Real World" costars, tweeted earlier this week.
Sasser gained prominence when he joined boyfriend Pedro Zamora in a commitment ceremony telecast on Nov. 3, 1994. Held at the "Real World" house, the event included the pair exchanging vows and wedding rings.
Zamora, who suffered from AIDS, died eight days after the episode was broadcast.
The "Real World" episode introduced many young people to the idea of gay marriage and was telecast years before the issue attracted mainstream political attention. In 1996, a national poll found 68% of respondents opposed to gay marriage. By 2012, the figure had dropped to 48%.
