Succession earned the prestigious best drama trophy and The Bear dominated comedy honours as Hollywood handed out the annual awards, the top accolades for television.
Snook's co-stars Kieran Culkin and Matthew Macfadyen also won acting trophies for their roles as part of the wealthy but miserable Roy family, who are in a cutthroat battle for control of a global business empire.

"It was a great sadness to end the show, but it was a great pleasure to do it," Succession creator Jesse Armstrong said on Monday.
The Bear, the story of a fine-dining chef trying to turn around his family's Chicago sandwich shop, also landed six awards, including best comedy series.
Star Jeremy Allen White was named best actor in a comedy, and his co-stars Ayo Edebiri and Ebon Moss-Bachrach won supporting actress and actor, for the first season of the show.
"I am so proud, so full of gratitude, to be standing in front of you all," said White, who plays chef Carmen "Carmy" Berzatto. "I love the show so much."

Road rage drama Beef won best limited series, one of its five awards for the night. Stars Steven Yeun and Ali Wong claimed acting trophies.
The top TV honours were broadcast live on the Fox network. The show was postponed from September because of Hollywood labour disputes last year.
Several Black actors won awards at the ceremony, which coincided with the US holiday commemorating civil rights leader Martin Luther King Jr.
"Everyone having fun at the chocolate Emmys tonight? We are killing it tonight!" said host and former "Black-ish" star Anthony Anderson.Â
