TODAY IN QUEER TV HISTORY
DAYS OF OUR LIVES, 5/30/1977, NBC
This week in 1977, this daytime soap was airing a story about a lesbian, Sharon, who'd married a man out of social pressure but was attracted to her straight best friend. Sharon had never accepted her own feelings for women.
In this episode, Sharon had been hospitalized after a suicide attempt. Therapist characters talked about how some people think being gay is a mental illness though it is not and that she needs to accept herself. This was about 3 years after homosexuality was declassified as an illness.
In the next episodes her husband can't cope with her sexuality and tries to pull her out of the hospital, beyond the reach of the supportive liberal psychologists. Sharon and Karl were written off of the series soon thereafter.
As far as I can tell, the first sustained, multi-month queer character on a soap came six years later, on ALL MY CHILDREN.
