Friday night's Late Late Show saw viewers donate €2m to Pieta to help its work preventing suicide and self-harm.
On Friday night the plaza at RTÉ was covered in lights, with each light representing a person who had died by suicide in Ireland in 2019.
Opening the show, host Ryan Tubridy told viewers: "Your donations tonight are essentially making sure that help remains available and can grow to meet the needs of all of us after a difficult and challenging start to the year. Every cent donated tonight will fund therapy hours at Pieta and ensure that their 24/7 crisis helpline remains open."
Guests on the show included Pierce Brosnan, U2's Adam Clayton, former President Mary McAleese and Commander Chris Hadfield, who all talked about coping during the Covid-19 emergency. Singers Mary Black, Frances Black, Mary Coughlan and Sharon Shannon also discussed mental health, with Pieta client Paul McEvoy telling his story.
At the end of the show, Ryan Tubridy said: "I'm not going to lie to you, we hoped if we could get €250,000, and shake the buckets that couldn't be shaken tomorrow [for Darkness Into Light walk], we would have been more than happy, because we have asked a lot of the Irish people week in and week out.
"As the show has been going on, the figures have kept going up and up and up. I cheekily suggested we might make it to €1 million...
"You at home, we salute you. It's beautiful. Thanks everybody. Remember you are not alone."
