NBC declined to air a public service announcement from the National Suicide Prevention Network, which requested the network air the spot after its tribute to the late Robin Williams during the Emmy Awards, according to The Hollywood Reporter.

“Collectively we decided to celebrate the life of Robin Williams, not his death or, more to the point, the way he died,” said a network spokesperson. “The Emmys telecast is a celebration, and the ‘In Memoriam’ section of our show is an important one. We believe we honored Robin in the right away. Suicide is a serious issue, but we decided not to dwell on that — or its prevention — in this particular forum.”

The tribute was delivered by Billy Crystal, a close friend of Williams. The comedian and actor committed suicide earlier this month at his home, as previously reported. His wife later revealed that he had been suffering from the early stages of Parkinson’s disease.
