Tucker Carlson said that there is likely evidence that social media executives knew but disregarded possible issues their products could cause, such as addiction and psychological damage.

Former Facebook president and billionaire Sean Parker said in a recent interview that social networks have the power now to alter society and not for the better.

"I don't know if I really understood the consequences of what I was saying, because [of] the unintended consequences of a network when it grows to a billion or 2 billion people and ... it literally changes your relationship with society, with each other ... It probably interferes with productivity in weird ways," Parker is quoted as saying. "God only knows what it's doing to our children's brains."

Carlson noted how Congress called executives from R.J. Reynolds and Philip Morris to testify in 1994 about whether they knew about the addictive and carcinogenic side effects of tobacco use.

The tobacco compaines later paid out huge sums of money over the issue.

He said social media use has been connected to "social maladjustment" and that suicide rates for teens have increased in an era of cyberbullying.

Carlson pointed out that Parker said in the interview that he and Facebook CEO Mark Zuckerberg knew their product addictive and harmful.

He asked why such executives haven't been called before Congress in a similar way as Big Tobacco.
