When someone watches your YouTube video while inside the Sizzle app, the video is programmable to be interactive in many different ways. Look through the Sizzle Gallery of Ideas for suggestions on how a programmed video can deliver significant interactivity. One of the most useful purposes for this is to enable the viewer to instantly purchase merchandise while the video is playing and presenting the merchandise options for sale. Such as a fashion show where the models walk a runway and each outfit may be purchased as they appear. Or a sales video that shows of products and enables your users to click and buy.
