I was reading some Dc Comics today and I got to thinking about the big 3. I am a fan of Batman and Superman and a casual fan of Wonder Woman and they are known as Dc's Big 3. They have been around since the late 30's and early 40's. What is it about these characters that have had them last 80 or so years. There were a ton on Heroes in the Golden Age for many different companies, but what was it about these three that kept them going after the other heroes faded from the pages. Many of the stories for these 3 heroes in the 50s and even into the 60s were flat out goofy and odd. So why did they stick around for so long?
Now I know the JSA has been around in some form or another for a long time but they have not been as Consistent as the big 3. And on the Marvel Side they have Golden Age Captain America and Namor on the pages today but they are not as popular as Dc's Big 3. At least Namor is not.
So what is it about these 3?
