The options for mediated delivery can be divided into two categories: prerecorded and real time. A prerecorded (also known as asynchronous) mediated presentation is recorded by the speaker for later viewing by one or more audiences. For example, a speaker might create a podcast or a YouTube video of a presentation. If you are taking an online public speaking class in which you will be recording your speech assignments and submitting them to your instructor, you will be delivering a prerecorded speech.

A real-time (also known as synchronous) mediated presentation is delivered directly to the audience as the speaker presents the message from a remote location—for example, a presentation during a videoconference or a speech presented to a group via Skype. These speeches have a number of similarities to F2F presentations, but there is one crucial difference—the audience and speaker are not together.

Mediated presentations pose both opportunities and challenges, and these can vary depending on whether they are in a prerecorded or real-time format.
