After taking a look at how Detective Comics Inc. started, and was it ever a brief history we move on to what happened after Superman, Batman, and Sandman(among others) ushered in the Superhero and the Golden Age.
Many things brought on the Golden Age of Comics, but one big important one was National Allied Publications mergring with Detective Comics Inc to form National Comics which in turn absorbed a affiliated concern, Max Gaines and Liebowitz's All American Publications. This happened in 1944, and in that same year Gaines let Liebowitz buy him out and only kept Picture Stories from the Bible as the foundation of his own new company which would be called EC Comics.

Liebowitz's quickly took charge and had a merger between All American and Detective Comics into National Comics as mentioned above but didn't stop there, He organized National Comics, Independent News, and all their affiliated firms into a single corporate entity named National Periodical Publications which would become publicly traded on the stock market in 1961. Though it had the official names such as National Comics and National Periodical Publications the company decided to brand itself as "Superman-DC" as early as 1940 and started being called DC comics, colloquially as DC comics years before the official adoption of that name in 1977.
