Marketplace Tech host Molly Wood talks to Dan Lockney, who leads the Technology Transfer Program.

Politicians, the public and regulators are all starting to see the power of social media companies. Particularly Facebook. That company said last week it would give Congress thousands of political ads linked to a possible Russian propaganda campaign.

But it’s looking more and more like Facebook’s days of sell first, apologize later could be coming to an end. We talk about the social pressure on Facebook to change.

There are whole new systems of money being traded in the digital world. Companies can create their own cryptocurrency and sell it to the public in an initial coin offering.
