The Rex Factor Podcast focuses on the history of the monarchs of England. The producers write:

Welcome to Rex Factor, a fun and informative history podcast where we review all the kings and queens of England from Alfred the Great to Elizabeth II and now, in our second series, of Scotland from Kenneth MacAlpin to James VI.

In each episode we look at one monarch, going over their life and reign before reviewing them on a number of factors:

• Battleyness – how good they are in battle and warfare
• Scandal – their notoriety and tendency towards naughtiness
• Subjectivity – how well and justly they ruled (i.e. would you want to be their subject?)
• Longevity – how long they ruled for
• Dynasty – how many legitimate, surviving children they had

And then, finally, we considered whether or not they have that certain something, that lasting legacy, the star quality that we call the Rex Factor.
