A webinar is a scaleable method of delivering content in real time. These can often be superior to in-person panel discussions since, as you can see in this mock-up (pretend each photo is a real-time video stream), viewers will never forget who is speaking, they can discuss the content with each other without disturbing others or the panelists, and they can easily pose questions to the panelists. Someone can even filter questions behind the scenes and post the best ones.
