The criterion for entry into the HOF is a combination of:
Mainstream popularity, being considered a great podcaster or contributor to the industry by their peers, or excelling in the medium of podcasting, as well as having historical significance in a positive manner.
Candidates should have something to offer in all three of the categories mentioned, or be so outstanding in one or two that they deserve inclusion.
To be eligible for entry into the HOF, a nominee must have completed five years since their first involvement in the medium, but longevity should not be considered a qualification in and of itself.
