Something historic will happen this Saturday, Oct. 11, in honor of National Coming Out Day: At least seven cable networks will air supportive coming out public service announcements, making this the largest national one-day television promotion ever for LGBT equality. Fox Reality Channel, IFC, Lifetime, The N, SCI FI Channel, Sundance Channel, USA Network and various ABC affiliates will air GLAAD's "Be an Ally & a Friend" PSAs on Saturday. Several of the networks also aired the celebrity spots throughout the week. The spots feature 22 personalities, such as T.R. Knight, Marlee Matlin and Martina Navratilova, sharing with viewers the importance of accepting gay friends and family members. This is the 20th Annual National Coming Out Day, observed every October 11. The day was established in 1988 to commemorate the first anniversary of the second national march on Washington for LGBT rights. "National Coming Out Day gives us a vital opportunity to talk about ensuring that lesbian, gay, bisexual and transgender people feel comfortable being open about who they are with their friends and families and in their communities," says GLAAD President Neil G. Giuliano. "Thanks to the generosity of our broadcast partners, we have a tremendous opportunity to reach Americans across the country with a message of inclusion and acceptance."
