What does the DC in DC Comics stand for?

The answer is: Detective Comics. After a couple of other previous names, entrepreneur and pulp comic writer Major Malcolm Wheeler-Nicholson finally landed on Detective Comics as the name for his comic book company, launching the name alongside an anthology of, you guessed it, detective stories.People began referring to it at DC Comics not long after, but it wasn’t until 1977 that they officially changed the name.Source
