Interactive or how do we influence each other

As interactive as possible. I understand it like people can influence each other in a different way. When we listen to the radio news we try to understand the news and later we can even interprete it. But radio or television give us only one way communication as we can only possible see or hear the information, but we can’t influnce this information. In other words we can’t correct it or even give our own points or highlight the most important key points from this information. In this case we can possibly say that radio and television is not interactive or partly interactive. Personally I like classical example of interactivity is conversation between people. In this case we can argue, complain or disagree. During conversation we have a chance to express ourselves and give our own point of view. And who knows it is possible that exactly your contribution will influence everyone else even media!
