What is an online seminar or presentation that allows remote engagement called?

The term that accurately describes an online seminar or presentation designed for remote engagement is "webinar." Webinars typically allow participants to view presentations, ask questions, and interact with speakers in real time through the internet. They often include visual elements such as slides and can accommodate a large audience, providing a platform for education, training, or information sharing.

A workshop, while similar, usually implies a more hands-on, interactive format that might take place in-person or online but focuses on skill development in a more intimate group setting. A podcast, on the other hand, is primarily an audio format that is often pre-recorded and lacks the live interactive component characteristic of a webinar. Lastly, a symposium refers to a formal meeting or conference where various experts present their research or findings but does not necessarily imply the online interactivity that a webinar does. Thus, the correct identification of a webinar encapsulates both its interactive and digital nature, making it the appropriate choice.
