The Home Secretary wants a tough crackdown to make the companies sweep the net and take down such posts for fear they are encouraging more attacks.
He told the BBC's Newsbeat: "I went over to the US myself and spoke to the five tech giants.
"I said you need to do more, use your own technology to sweep the net and find these videos and take them down."
He said they were doing an "incredible job" on some issues but they needed to do much more or new laws would come.

"My message to these companies is we are going to legislate – and how far we go depends on what you decide to do now," he vowed.

"My eldest daughter has started going out more than she used to," he said.
"But I do worry and there are some nights that I've stayed up into the early hours of the morning waiting for her to get back home."

"We have a dedicated process for the police to flag videos directly to our teams because we often need specialist context from law enforcement to identify real-life threats.
"We do not want our platform used to incite violence."
