I've produced or streamed thousands of corporate events since 1998. Since then, I've seen the different use cases of live video change. It went from an "add on" to a business or marketing event, to a core strategy and advanced way to connect with consumers around the world. But when marketers, brands and publishers that I speak are considering live video, their first question isn't about the benefits of live. Instead, they ask when they should use live video -- and when VOD is more important to reach a broader audience.
