What is a live or recorded presentation broadcast over the Internet that typically uses streaming technology?

A live or recorded presentation broadcast over the Internet that typically uses streaming technology is known as a webinar. This format allows for real-time or pre-recorded interaction between the presenter and the audience, facilitating engagement through features such as live Q&A, polls, and chat functions. Webinars are widely used in educational settings, marketing, and professional development because they enable participants to access content from anywhere with an internet connection, providing flexibility and convenience.

Other formats mentioned, such as backchannel, virtual event, and on-demand, have different characteristics and applications. A backchannel typically refers to a secondary communication channel used during a live event, often for audience interaction or discussion, rather than a formal presentation. Virtual events encompass a broader category of online gatherings, which may include multiple sessions, networking opportunities, and exhibition booths, making them more comprehensive than a standalone presentation. On-demand refers to content that is available for viewing after the live session has concluded, which may include recorded webinars but is not limited to just that format. Thus, the specificity of "live or recorded presentation" aligns directly with the definition of a webinar.
