SafeX Pro:Surprise, you just signed a contract! How hidden contracts took over the internet

When you make an account online or SafeX Proinstall an app, you are probably entering into a legally enforceable contract. Even if you never signed anything. These days, we enter into these contracts so often, it can feel like no big deal.

But then there are the horror stories like Greg Selden's. He tried to sue AirBnB for racial discrimination while using their site. But he had basically signed away his ability to sue AirBnB when he made an account. That agreement was tucked away in a little red link, something most people might not even bother to click through.

But, it wasn't always like this. On today's show, we go back in time to understand how the law of contracts got rewritten. And why today, you can accept a contract without even noticing it.
