I like to think of context as a cookie that gets passed back and forth

The video's mention it and the Watson documentation talks about it but it is a little confusing to start with. It does this using a JSON format which can include basically any attribute you want to put into it. If you are working with a chat app in the browser the browser can take care of the cookie for you.
