Tech billionaire Peter Thiel says he only allows his children 1.5 hours of screen time a week

• Peter Thiel said he only lets his kids use screens for 1.5 hours a week.
• There is a growing push by US officials to regulate the use of social media among children.
• Other tech CEOs, like Evan Spiegel and Sundar Pichai, also limit their children's screen time.

Social media for thee, but not for me. Or my kids, says Peter Thiel.

During a conversation with journalist Andrew Ross Sorkin at the Aspen Ideas Festival in Colorado on Thursday, Thiel, the cofounder of PayPal and the first outside investor in Facebook, revealed that he doesn't like his kids spending too much time in front of screens during the week.
