The Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, has released two videos to help celebrate the 25th anniversary of National Coming Out Day.

Founders Robert Eichberg and Jean O'Leary chose the date of October 11 for National Coming Out Day because it is the anniversary of the 1987 National March on Washington for Lesbian and Gay Rights.

In one of the videos, released on Thursday, HRC takes a look at the public coming outs of celebrities, including Ellen DeGeneres, Pedro Zamora, k.d. lang, Lance Bass, Clay Aiken, Adam Lambert, Wanda Sykes, Ricky Martin, Lana Wachowski and Chaz Bono, as well as everyday folks on YouTube.

In one clip, ABC News' George Stephanopoulos is seen asking NBA free agent Jason Collins: “You always knew that you were gay?”

“Yeah,” Collins answered. “I sort of describe it as you know that the sky is blue but you keep telling yourself that it's red. But when you finally get to that point of acceptance, there's nothing more beautiful.” (The video is embedded on this page. Visit our video library for more videos.)
