Slideshare is another popular tool for creating and sharing slideshow presentations. Its basic features allow for designing and sharing, but premium features allow for analytics and embedding of video.
This presentation tool is primarily aimed at businesses. The free version allows for basic designing and sharing of presentations, while the advanced version provides more control over the presentations and measures usage and viewership.
Vialogue = "video plus a dialogue." Vialogue creators upload a video, and then insert comments, surveys, and open-ended questions throughout. These can be embedded into websites or shared among collaborators.
