What characterizes a webcast in digital events?

A webcast is primarily defined by its structure and delivery method, which often involves a presenter broadcasting to a large audience without the same level of interactivity as other formats, such as webinars or live-streamed events. The nature of webcasts typically features a one-to-many communication model, where a small group of speakers shares information with a sizable audience. Due to this structure, audience interaction is generally limited, focusing instead on the content presented.

The other options presented are characteristics that do not align with the webcast format. For instance, high levels of audience engagement and focused discussions in small groups are more representative of interactive events like webinars, where interaction and conversation are encouraged. Face-to-face interaction is not a hallmark of webcasts, as they are designed for online consumption and typically do not involve the in-person dynamics found in live events.
