The “Call to Action”’ is used for telling the audience what their next step is, based on what they heard/see so far. For example, their “next step” might be to fill out a contact sheet as noted above for continued follow up. Bottom line is that you want to direct the audience to do something with the information they just heard instead just saying “Cool Demo” and moving on. The Call to Action is used to turn a passive listener into an active participant, focusing on using the technology in their next product feature.
