a. do not require a live presence, yet offer a friendly human face.

Explanation:

With podcasts, one does not have to be live and can simply do a pre-recording. This means that it can be repeated over and over and people can simply watch it at their convenience unlike live appearances.

This is beneficial to businesses as it means that they get to reach out to more people because apart from the convenience it offers, the friendly human voice that podcasts offer will entice people all the more.
