Leading media and technology executives spoke about the importance of fostering safe conversations online during Variety‘s Silicon Valleywood presented by PwC on Tuesday.

Speaking to Variety‘s Janko Roettgers, Kelly Day, the president of Viacom Digital Studios said her team “acknowledges and understands that as partners and as content creators the challenges that platforms like Twitter, Youtube, Facebook, Instagram face in keeping our kids safe and creating environments that foster safe conversations and dialogue between people.”

“This is an incredibly difficult task, we understand that,” she said.

Kay Madati, the head of content at Twitter piggybacked on Day’s statements, referring to Twitter CEO Jack Dorsey’s commitment to healthy conversations on the app. “It’s absolutely true that health and the ability to have conversations on our platforms is our priority,” Madati said.
