The Comic Book Showcase is a joint project between the Marvel and DC wikias.

And they focus on different topics each episode. This one happened to be about a DC-related thing. Other episodes have been about Guardians of the Galaxy, Invincible, X-Men: Days of Future Past, or Captain America: The Winter Soldier.
